Value Collection R57700847 Coiled Spring Pin 0.25in 1.125in

Product Description

The VALUE COLLECTION R57700847 is a coiled spring pin sized at 0.25 inches in diameter and 1.125 inches in overall length, manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins are slotted cylindrical fasteners that compress radially during insertion and exert outward spring force against the host bore wall, locking the pin in place without adhesive or secondary fasteners. This design allows the pin to absorb shock and vibration loads, making it a reliable choice for mechanical assemblies that see dynamic or cyclic stress. Technicians and assemblers working in maintenance, repair, and manufacturing operations will find this pin suitable for a wide range of general-purpose fastening tasks.

This coiled spring pin is intended for use in industrial and mechanical applications where a standard inch-series roll pin is required. Typical installations include shafts, linkages, hinges, and clevis connections in light to medium-duty assemblies. The 1070-1090 alloy steel construction provides adequate strength and resilience for general mechanical applications. This item is sold individually but carries a minimum order quantity of 50 units, making it appropriate for stocking or production-line use rather than single-piece repair.

Key Features

• 0.25 inch nominal diameter fits standard quarter-inch bored holes in inch-series assemblies
• 1.125 inch overall length suits moderate-depth shaft and linkage applications
• 1070-1090 alloy steel construction delivers good tensile strength and spring resilience
• Plain finish with no coating or plating — suitable for dry or lightly oiled environments
• Coiled design distributes insertion stress across multiple wraps, reducing bore damage compared to slotted roll pins
• Inch system of measurement — directly interchangeable with standard fractional-inch pin specifications

Compatibility

Designed as an OEM-style replacement or general-purpose coiled spring pin for any mechanical assembly requiring a 0.25 inch diameter, 1.125 inch long inch-series pin in alloy steel.

Installation Notes

Coiled spring pins are typically installed using a pin punch and hammer or a hydraulic press, depending on fit tolerance and assembly access. Always ensure the receiving bore is clean and free of burrs before driving the pin. Wear appropriate eye protection during installation, as pins can eject under spring load if misaligned. When removing the pin for service, use a proper pin punch matched to the pin diameter to avoid bore damage.
