Value Collection R57700741 Coiled Spring Pin 0.0938 in

Product Description

The VALUE COLLECTION R57700741 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. It measures 0.0938 inches (3/32 inch fraction) in diameter and 3/8 inch in overall length. Coiled spring pins are slotted, roll-formed fasteners that compress upon insertion and exert radial spring force against the host bore wall, creating a secure, vibration-resistant fit without adhesive or locking hardware. Machinists, millwrights, and general assembly technicians use these pins to align components, retain shafts, or act as stop pins in light- to medium-duty assemblies.

This pin is suited for use in precision mechanical assemblies where a small-diameter, short-length retention or alignment fastener is required. Typical applications include machine components, linkages, hinges, and fixture assemblies in industrial and manufacturing environments. The inch-system sizing makes it compatible with standard inch-dimensioned bores and tooling. The 1070-1090 alloy steel construction provides adequate shear strength for general-purpose mechanical applications that do not require military-specification fasteners.

Key Features

• Coiled spring design provides consistent radial pressure against the bore wall for vibration-resistant retention
• 1070-1090 alloy steel construction offers solid shear strength for general-purpose mechanical use
• Plain finish — no coating or plating — suitable for interior or protected applications
• Compact 0.0938 inch diameter and 3/8 inch length fits tight-clearance, small-bore designs
• Inch-system dimensioning aligns with standard inch-based tooling and bore specifications

Compatibility

Designed as a general-purpose coiled spring pin for standard inch-dimensioned bores requiring a 0.0938 inch diameter, 3/8 inch long retention or alignment fastener. Does not meet military specifications.

Installation Notes

Installation is typically performed by machinists or assembly technicians using a pin punch and hammer or an arbor press. The receiving bore should be sized to the pin manufacturer's recommended hole tolerance to ensure proper spring compression and retention force. Always deburr the bore entry chamfer before driving the pin to prevent shearing the coil edges. Do not reuse a coiled spring pin that has been fully driven and removed, as repeated cycling degrades the spring force.
