Value Collection c57700821 Coiled Spring Pin 25-pack

Product Description

The VALUE COLLECTION c57700821 is a coiled spring pin made from 1070-1090 alloy steel with a black oxide finish. Coiled spring pins are slotted, rolled fasteners that compress on insertion and exert radial pressure against the host bore wall, creating a secure, vibration-resistant fit without adhesives or additional hardware. At 1-1/2 inches long and 3/16 inch in diameter, this pin suits medium-duty fastening and alignment tasks across a range of mechanical assemblies. Each package contains 25 pins. Installation requires no special tooling beyond a standard pin punch and hammer or press.

Coiled spring pins are used in general mechanical assembly, maintenance, and repair work across industrial, commercial, and light-manufacturing environments. Common applications include shaft-to-hub connections, linkage alignment, clevis pins, and hinge retention in metal assemblies. This pin is dimensioned for use in applications where a 3/16 inch bore diameter is specified. Machinists, millwrights, and maintenance technicians are the typical installers. The black oxide finish provides mild corrosion resistance and reduces galling during installation.

Key Features

• Coiled spring design provides consistent radial force against bore walls for vibration-resistant retention
• 1070-1090 alloy steel construction for reliable strength in medium-duty fastening applications
• Black oxide finish offers mild corrosion resistance and a low-glare surface
• 1-1/2 inch overall length suits a wide range of standard bore depths
• 3/16 inch diameter fits common bore specifications in mechanical assemblies
• Sold in a package of 25 pins for stocking and repeat-use applications

Compatibility

Designed as a standard coiled spring pin for use in any mechanical assembly specifying a 3/16 inch diameter, 1-1/2 inch long coiled spring pin in inch measurement systems.

Installation Notes

Install using a pin punch sized to the pin diameter and a hammer or arbor press — avoid driving with an oversized punch that contacts the bore wall. Ensure the host bore is clean and free of burrs before insertion. For removal, drive the pin through the bore or use a pin extractor; do not attempt to pry laterally, as this can deform the coil. No special certifications or code compliance requirements apply to standard spring pin installation.
