DIN 6799 Fasteners

DIN 6799 is the standard DIN specification for E-Clips (also known as ‘E’ type circlips). They make up the D1500 series of fasteners.

How are they used?

They are inserted on to the side of a shaft, into a groove. They do not contain lugs, meaning circlip pliers do not always need to be used, making for an easier installation.

What materials are available for these parts?

  • Carbon Spring Steel
  • 420 Stainless Steel
  • 316 (A4) Stainless Steel
  • Beryllium Copper
  • Inconel
  • Titanium

Where can I purchase E-Clips?

Directly from our website.

Slotted Spring Pin Standards

Slotted Spring 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 Design of Internal Circlips

Internal Circlips are an open ring with two lugs at the end, facing internally.

These circlips are designed to be fitted into bores with the circlip fitting into the groove of the bore.

The internal lugs allow the circlip to be compressed with circlip pliers to aid with the installation and removal of the circlip.

Materials available for internal circlips include, carbon spring steel, stainless steel (including 316 grade stainless), inconel and titanium.

Other varieties of internal circlips are also available, including inverted lug and increased abutment circlips.

Purpose of a Split Cotter Pin

 A Split Cotter Pin is a simple fastening device to prevent parts being released off the end of a shaft. Alternatively, they can be very useful to prevent nuts coming undone off a threaded fastener by simply drilling through nut and bolt. The outside diameter of the pin is made marginally smaller than the hole size to give easy fit. Once inserted the legs are bent over in opposite directions to complete the fastening. 

They can also be used in conjunction with Clevis Pins, as shown below.

We offer Split Cotter Pins in two materials, Mild Steel (with a bright zinc plate finish) or A2 Stainless Steel.
