Value Collection R57700697 Slotted Spring Pin 1/16 in

Product Description

The VALUE COLLECTION R57700697 is a slotted spring pin manufactured from 1070-1090 alloy steel with a plain finish. Slotted spring pins are hollow, longitudinally slotted fasteners that compress radially during installation and exert spring force against the bore wall to maintain their position without threading or adhesive. This pin measures 0.0625 inches in diameter and 0.25 inches in length. It is used in precision mechanical assemblies to retain shafts, align components, or serve as a stop or hinge element. Machinists, millwrights, and mechanical assemblers typically install these pins using a pin punch and hammer or an arbor press.

This slotted spring pin is suited for light-duty fastening applications in machinery, equipment, and tooling where a compact, self-retaining fastener is required. The 1070-1090 alloy steel construction provides the hardness and spring characteristics necessary for reliable radial retention in steel and aluminum bores. The plain finish is standard for general industrial use where corrosion exposure is minimal or where the assembly will receive a secondary protective coating. This pin does not meet military specifications and is intended for commercial and industrial applications.

Key Features

• Slotted design compresses during installation for a friction-fit, self-locking hold in the bore
• 1070-1090 alloy steel construction delivers the hardness and spring tension required for radial retention
• 0.0625 inch (1/16 inch) diameter fits precision-machined bores in light mechanical assemblies
• 0.25 inch overall length suits shallow-bore and thin-wall component applications
• Plain finish is compatible with secondary coatings or use in dry, low-corrosion environments
• Inch measurement system; UNSPSC Code 31163201

Compatibility

Designed as a standard commercial-grade slotted spring pin for general industrial and mechanical assembly applications requiring a 0.0625 inch diameter, 0.25 inch long pin. Does not meet military specifications.

Installation Notes

Slotted spring pins are installed by a machinist, millwright, or mechanical assembler using a pin punch sized to the pin diameter and a hammer, or with an arbor press for controlled seating. Always ensure the receiving bore is clean and correctly sized to the pin diameter before installation. Do not use an oversized punch that contacts the bore wall. Once seated, the pin should sit flush or slightly below the surface of the component unless the application requires a proud installation.
