Value Collection c57700817 Coiled Spring Pin 25-pack

Product Description

The VALUE COLLECTION c57700817 is a coiled spring pin designed for use in mechanical assemblies where a resilient, slotted fastener is needed to secure components in a drilled hole. Made from 1070/1090 alloy steel with a black oxide finish, this pin measures 1-1/4 inches in length and 3/16 inch in diameter. The coiled design allows the pin to compress on installation and exert radial pressure against the hole wall, creating a secure, vibration-resistant fit without permanent deformation. Machinists, maintenance technicians, and assembly professionals install these pins across a wide range of industrial and mechanical applications.

Coiled spring pins are used in shafts, linkages, hinges, and structural assemblies in both light and heavy industrial settings. The 3/16 inch diameter and 1-1/4 inch length make this pin suitable for moderate-load applications where a reusable, removable fastener is preferred over a solid or roll pin. This listing includes a package quantity of 25 pins, making it appropriate for bench stock, MRO replenishment, or production use. The black oxide finish provides mild corrosion resistance in dry or lightly oiled environments.

Key Features

• Coiled spring design compresses for installation and exerts radial holding force against the hole wall
• 1070/1090 alloy steel construction provides strength and resilience for repeated installation and removal
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• 1-1/4 inch overall length and 3/16 inch diameter for moderate-load fastening applications
• Package of 25 pins suitable for bench stock or MRO replenishment
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard coiled spring pin for use in any drilled-hole mechanical assembly requiring a 3/16 inch diameter pin with 1-1/4 inch length, measured in the inch system.

Installation Notes

Coiled spring pins are installed by machinists and maintenance technicians using a pin punch and hammer or a hydraulic press, depending on fit tolerance and material. Always ensure the receiving hole is drilled and deburred to the correct diameter before driving the pin. Depressurize, de-energize, or secure any assembly before pin installation or removal to prevent unintended movement. Avoid reusing pins that show visible deformation or splitting beyond normal compression.
