Value Collection R57700725 Coiled Spring Pin 1070-1090 Alloy Steel

Product Description

The VALUE COLLECTION R57700725 is a coiled spring pin designed for use in precision fastening and alignment applications across mechanical assemblies. This pin measures 0.0625 inches in diameter and 0.3125 inches (5/16 inches) in length, manufactured from 1070-1090 alloy steel with a plain finish. The coiled design provides radial flexibility under load, allowing the pin to absorb shock and vibration while maintaining a secure fit in the host bore. Machinists, maintenance technicians, and assembly professionals install this type of pin in shafts, linkages, and structural components where a reliable, removable fastener is required.

This coiled spring pin is suited for light-duty to medium-duty mechanical assemblies in industrial, commercial, and OEM manufacturing environments. Its compact 0.0625 inch diameter makes it appropriate for small-bore applications such as instrument mechanisms, light machinery linkages, and precision component alignment. The inch measurement system designation confirms fitment in standard imperial-dimensioned bores. This pin does not meet military specifications, making it appropriate for commercial-grade applications where MIL-spec compliance is not required.

Key Features

• 0.0625 inch diameter and 0.3125 inch (5/16 inch) overall length for compact fastening applications
• Coiled construction provides radial flexibility and absorbs shock and vibration in dynamic assemblies
• 1070-1090 alloy steel material delivers strength appropriate for commercial-grade mechanical use
• Plain finish with no coating, suitable for standard environmental conditions
• Inch measurement system for direct fitment in imperial-dimensioned components

Compatibility

Designed as a commercial-grade coiled spring pin for standard imperial-dimensioned bores in light-duty to medium-duty mechanical assemblies. Does not meet military specifications.

Installation Notes

Coiled spring pins are typically installed by machinists or mechanical maintenance technicians using a pin punch and hammer or a hydraulic press, depending on bore tolerance and assembly access. Ensure the receiving bore is clean and dimensionally correct before driving the pin to avoid deforming the coil. Do not reuse a coiled spring pin that has been removed, as the coil geometry may be compromised. Follow applicable machinery safety lockout and tagout procedures before servicing any assembly containing these pins.
