Value Collection R57700795 Coiled Spring Pin 5/32 in

Product Description

The VALUE COLLECTION R57700795 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins are slotted cylindrical fasteners that compress radially during installation, then exert outward spring force against the host bore wall to hold position. This pin measures 0.1563 inches in diameter — equivalent to 5/32 inch — and 1 inch in overall length. It is used in mechanical assemblies where a removable or semi-permanent pin retention solution is needed without threading. Machinists, millwrights, and maintenance technicians install these pins in production equipment, jigs, fixtures, and general mechanical assemblies.

Coiled spring pins of this diameter and length are commonly specified in light-duty to medium-duty mechanical assemblies. Typical applications include alignment and retention of shafts, levers, linkages, and collars in industrial machinery, hand tools, and fabricated metal assemblies. The alloy steel construction makes this pin suitable for applications requiring moderate shear strength and resilience under dynamic or vibrating loads. This pin follows inch-system dimensioning and is appropriate for bores sized to accept a 5/32-inch nominal coiled spring pin.

Key Features

• Coiled spring design provides radial retention force without permanent deformation of the bore
• 0.1563 inch (5/32 inch) diameter fits standard inch-system bores
• 1 inch overall length suits a wide range of shaft and wall thicknesses
• 1070-1090 alloy steel construction delivers moderate shear strength and spring resilience
• Plain finish — no plating or coating that could add dimensional variation
• Does not meet military specifications — intended for standard commercial and industrial use

Compatibility

Designed as a standard inch-system coiled spring pin for use in any mechanical assembly calling for a 5/32-inch nominal diameter coiled pin, 1 inch in length, in 1070-1090 alloy steel with a plain finish.

Installation Notes

Coiled spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore diameter is machined to the correct tolerance for the nominal pin size before installation. Deburr the bore entry to prevent galling or pin damage during insertion. Always wear appropriate eye protection when driving pins, as spring pins can eject unexpectedly under improper seating force.
