DIN 11024 Spring Pin (Linchpin), Form D

The DIN 11024 needle-type spring cotter pin is widely used in machine building and other industries. The product consists of two elements: a straight part and a snap-fit part.

The straight part is inserted into a prepared hole, and the second part of the cotter pin snaps onto the component and secures it. The product is held firmly in place by the spring effect. Form D differs from form E in having two spring coils instead of three, while still providing reliable retention.

Manufacturing and application features

High-strength carbon steel is used to manufacture cotter pins of this type. The products can also be made from stainless steels of grades A2 and A4 — these alloys offer increased resistance to moisture, temperature fluctuations and acidic environments. A carbon steel product can additionally be fitted with a zinc coating to counter corrosion, which extends the service life of the fastener.

Spring cotter pins of this type have the following characteristics:

• The length of the straight part can range from 42 to 150 mm — the main parameter for selection.
• The diameter of the cotter pin head ranges from 20 to 30 mm.
• The diameter of the metal rod from which the cotter pin is made can range from 2.5 to 8 mm.

This type of product is used in machine building, machine-tool manufacturing, automotive manufacturing and other industrial sectors. Cotter pins are also used in construction for fastening and securing various materials.
