Made from Stainless Steel (A2) with extended prong locking and a square cut tip. Designed for consistent performance in small assemblies.


Secure mechanical retention – with Extended Prong locking

Extended prong locking means one leg extends further along the shaft to increase interference in the assembly. The additional length helps hold the pin more firmly once spread.

Reduces axial movement under vibration and keeps small moving parts fastened during everyday use.

Durable corrosion-resistant finish – thanks to Stainless Steel (A2)

Stainless Steel (A2) is the specified material, giving a stable metal composition suited to typical workshop and outdoor environments. The metal retains shape and resists common forms of surface degradation.

Maintains integrity over repeated use and exposure, cutting down the need for frequent replacements.

Predictable fit and sizing – with DIN94 tolerance and M2 dimensions

Manufactured to DIN94 tolerance and listed as M2 (2mm x 10mm), keeping diameters and lengths consistent across batches. Standard sizing aligns with common miniature fastener requirements.

Makes it straightforward to choose the correct pin for model-making, small gear assemblies and light repairs.
