Here at Caleb Components we stock a large range of Shim Washers to DIN 988 standard, Flat Washers to DIN 125 standard, Shakeproof (tooth lock) Washers and Single Coil Washers to DIN 127B standard (also known as Spring Lock Washers).

Our Shim Washers start from as small as 3mm x 6mm x 0.1mm up to 100mm x 120mm x 1mm. These are made from Carbon Steel with a plain finish. These are sold in small pack quantities for your convenience. For larger bulk quantities please send us an enquiry and we will be more than happy to help.

Not long ago, we also introduced Flat Washers Form A (DIN 125) to our range. Our Flat Washers are bright zinc plated. These are used to protect the surface of the parts being tightened. Sizes range from M2 to M20.

We now also stock Internal and External Shakeproof Washers (these are also known as Toothlock washers). By placing these washers under the head of a bolt/nut helps grip into the surface of the part being tightened, thus helps prevent loosening of nut, bolt or screw. External sizes include 4mm, 6mm, 8mm 10mm and 12mm and Internal sizes include 2mm, 4mm, 6mm, 8mm, 10mm and 12mm.

Caleb also supplies DIN 127B Single Coil Spring Tension Washers (also known as Spring Lock washers). Sizes ranging from 3mm up to 30mm. Sing Coil Spring Tension Washers compress when tightened offering a spring force between fastener and component thus helping to prevent loosening of nut, bolt or screw.

Please let us know if you have any enquiries for any of our parts.

Caleb Components offers a range of different type of disc spring washers.

The first range we supply is DIN 2093 Disc Spring Washers. These are a powerful conical washer used in minimal space with high force.
Standard material we offer is Carbon Steel with Phosphate and Oil finish.
Please check out our online store www.springfasteners.co.uk to see if we have a size to suit you.

Another range of Disc Spring we offer is our Ball Bearing Preload Disc Springs. Advantages of these include reducing number of components and simplifies fittings, take up manufacturing tolerances and quiets bearings.
These are offered in Carbon Spring Steel with Phosphate and Oil finish.

As well as the above range of Disc Springs, we can also offer DIN 6796 Heavy Duty Disc Spring Washers. Their ideal use is for bolted sections where they are put under the nut and/or bolt head to help prevent loosening.
Why not check out our range on our online shop to see if we have heavy duty disc spring to suit you. If not, please don’t hesitate to contact us with any enquires you may have. Again, also offered in Carbon Spring Steel with Phosphate and Oil finish.

We also offer, here at Caleb Components, both light duty and medium duty Serrated Safety Washers.
Using the same concept of the Disc Spring, the Serrated Safety Washer has the special feature of radial serrations on both surfaces. When tightened to near capacity these serrations bite into the mating surfaces, thus preventing the loosening of the screw due to vibration and other similar circumstances. Serrated Safety Washers offer a reduction in the outside dia thus corresponding with most screw head sizes, particularly hexagonal socket type screws.

We look forward to hearing from you with any enquires you may have.

Looking for the right type of pin for your application can sometimes prove difficult. At Caleb Components, we offer a large variety of different pin types.

Starting with Solid Dowel Pins which are hardened and ground and offer a precise fit into a well machined hole. Being hardened, these offer a good durable, long lasting fit and has the added strength of say that of a Spring tension pin.

The Spring Tension Pin however, offers a greater variety of flexibility as these pins are hollow and are manufactured from a hardened spring steel which close down when inserted into a standard drill hole. The uses of these pins can be varied to include such uses as a hinge pin or used a fixing pin.

Another popular type sold by us is the DIN 94 Split Cotter Pin and the use of this part is different to the two mentioned above. Split pins are used as a secure fixing device as it is generally located through a hole midway through a shaft and therefore stops the pin from falling out of its location. These are easily secured in place by bending both legs in opposite directions. Removal can be a little more difficult as legs cannot always be bent back into position and often pins might have to be cut in order to be removed.

Not quite as popular as the Split Cotter Pins, the Retaining Pins offer a simple removable device, as they are simply pushed through a hole in a shaft and the other leg will fit over the shaft to hold in place. These parts are Zinc Plated to offer general corrosion resistance and due to their flexibility can be used on numerous occasions.

I remember an incident many years ago, when working at a different fastener company a business who purchased from us several hundreds of pounds worth of Disc Springs. Within a week, we received a phone call from a very distraught customer who told us in no uncertain terms that the Disc Springs we supplied were shattering into hundred of small fragments.

Questioning the customer further, we discovered that they took it upon themselves to get the parts plated. Unfortunately what they didn’t realise was that you cannot simply electroplate this type of product. Even with hydrogen de-embrittlement, small fractures can occur within the Disc Spring. As soon as pressure is applied to the Discs, stress occurs and at this point the Disc is prone to fracturing.

Standard Disc Springs are phosphated and oiled as a finish, which is fine for normal indoor shelf life in dry non-humid conditions. However, where better corrosive resistance is required parts should be plated using non electro type methods such as mechanical zinc plate or delta tone for example.

We would be happy to discuss with you any plating / special material requirements you need according to your application.

Here at Caleb Components, we have now increased our Spring Tension Pin range.

We now offer Heavy Duty Spring Tension Pins to ISO 8752 (DIN 1481) Standard in both Carbon Steel and Stainless Steel. We also offer Light Weight Spring Tension Pins to ISO 13337 (DIN 7346) Standard also in Carbon Steel.

Larger sizes of Spring Tension Pins are available currently up to 50mm diameter and possibly beyond. Available in 4-6 weeks for non-stock items.

Although our current range for non-preferred sizes may be limited, we are always happy to offer a quotation for any requirements you may have. For example we can offer some pins with 7mm, 9mm and 13mm diameters.

As well as the more common materials as mentioned above, we can offer where necessary, parts in a higher grade stainless such as 316 (A4) Grade. This material for example, offers excellent corrosive resistant qualities and proves very useful in a marine environment. Some sizes may be available from stock.

Stock sizes available to order directly from springfasteners.co.uk or please send enquiries to us at sales@calebcomponents.com.

We look forward to receiving any enquiries you may have.

Disc Spring Washers; even the smallest sizes can pack a punch when it comes to load rating. Even sizes that start from 8mm outside diameter can offer up to nearly 450 newtons of force to flat. Despite relatively small sizes, they can offer huge forces compared to that of say normal Compression Springs.

Disc springs can be uses on a single basis or can be stacked in parallel (stacked the same way) will double the force of a single disc. To vary the arrangement further Disc Springs can also be stacked in series. For example, 10 single discs in series (back to back) would keep the force of a single disc but lengthen the deflection by 10 times.

Stack configuration is almost innumerable as such a wide variety of force and deflections can be made available by using any of the large size range available from Caleb Components. Again, unlike compression springs, which are of a fixed length, Disc Springs can be altered quickly and simply by adding or removing Discs from the stack.

As well as the standard DIN 2093 range, again Caleb Components can offer Ball Bearing Pre- Load, Serrated, and Heavy Duty Belleville Washers to DIN 6796.

Our company can offer full technical support and help and aid engineers to design the ideal stack for your components.

Slotted Spring Tension Pins are simply a single coil of steel with an open slot, this will enable the pin to reduce its diameter, so that it can be easily inserted into the appropriate size hole. The most common form of Spring Pin is the Heavy Duty type, and conform to ISO 8752 (DIN 1481) standards.

WHAT SIZE DO I ORDER?

Spring Tension Pins are listed by the hole size they are slotting into. For example, If you have a hole size of 6mm, you will need a 6mm Spring Tension Pin. Looking for technical assistance? Please contact us today and we would be happy to help!
