Zoro Select 5EA50 Spring Pin Pack

This pack supplies ten coiled spring pins made from 420 stainless steel with a plain finish. Each pin measures 1/4 inch in diameter and 1-1/8 inch in usable length. They suit assembly, repair and alignment tasks where a secure, reusable fastener is required. The chamfered ends help start the pin in a matching hole.

ASME B18.8.2 Compliant Coiled Pins

Manufactured to ASME B18.8.2 standards, these pins hold a nominal diameter of 1/4 inch with a shank length tolerance of +/- 0.010 inch. The chamfer diameter is 0.2429 inch and the maximum chamfer length is 0.065 inch. They fit holes with a minimum and maximum diameter of 1/4 inch. The coiled construction provides radial tension for a tight fit.

Stainless Steel Durability In Use

The 420 stainless steel resists corrosion during normal handling and service. Plain finish avoids plating debris in sensitive assemblies. Coiled design absorbs vibration and allows repeated installation and removal without damaging the hole. Pack of ten supports multiple joints or field spares.
