Value Collection R57700637 Slotted Spring Pin 3 in 5/16 in

Product Description

The VALUE COLLECTION R57700637 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins are hollow, longitudinally slotted fasteners that compress radially during installation and exert constant outward spring force against the bore wall to hold position without threading or adhesive. This pin measures 3 inches in overall length and 5/16 inch in diameter. It is a standard inch-system fastener used in mechanical assemblies across manufacturing, maintenance, and repair applications. Installation is typically performed by mechanical technicians and machine maintenance professionals using a pin punch and hammer or arbor press.

Slotted spring pins are used to secure components such as collars, gears, levers, and linkages onto shafts, or to align mating parts in structural and mechanical assemblies. This pin is suited for general industrial and commercial equipment maintenance where corrosion resistance is a priority. The 18-8 stainless steel construction makes it appropriate for environments with exposure to moisture or mild chemical contact.

Key Features

• 3 inches overall length in standard inch measurement system
• 5/16 inch diameter for a common shaft and bore size
• 18-8 stainless steel construction provides corrosion resistance
• Slotted design allows radial compression for secure, self-retaining fit
• Does not meet military specifications — suited for commercial and industrial use

Compatibility

Designed as a standard inch-system slotted spring pin for use in general mechanical and industrial assemblies requiring a 5/16 inch diameter, 3 inch long spring pin in stainless steel.

Installation Notes

Installation of slotted spring pins is typically performed by mechanical maintenance technicians. Power down and de-energize any equipment before servicing. Use a correctly sized pin punch or arbor press to drive the pin squarely into the bore to avoid deformation. Do not use an oversized punch, as this can damage the slot and reduce the pin's retention force.
