Value Collection R57700727 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700727 is a coiled spring pin designed for secure fastening in mechanical assemblies. This pin measures 0.0625 inches in diameter and 7/16 inches in overall length, manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins are slotted along their length and compress during installation to create a tension fit within a drilled hole, providing reliable retention without adhesives or secondary fasteners. Machinists, maintenance technicians, and assembly professionals install these pins wherever a removable or permanent drive-fit fastener is required in metal, plastic, or composite workpieces.

Coiled spring pins of this size are commonly used in light-duty to medium-duty mechanical assemblies, including linkages, hinges, shafts, and alignment fixtures. The 1/16-inch diameter and 7/16-inch length suit applications where a compact, low-profile fastener is needed in tight clearance areas. These pins are appropriate for both production assembly environments and field repair work across industrial, agricultural, and general manufacturing settings.

Key Features

• Coiled design provides radial compliance and absorbs shock and vibration loads
• 1070-1090 alloy steel construction offers good tensile strength and hardness for drive-fit retention
• Plain finish suitable for dry or lightly lubricated environments
• Compact 0.0625-inch diameter fits tight-clearance bore applications
• Inch measurement system for compatibility with standard drill and reamer sizing

Compatibility

Designed as a standard coiled spring pin for use in any application requiring a 0.0625-inch diameter drive-fit pin in a drilled hole sized to inch specifications.

Installation Notes

Installation is typically performed with a pin punch and hammer or a pneumatic pin driver sized to the pin diameter. The receiving hole should be drilled and reamed to the appropriate tolerance for a coiled spring pin fit before installation. Always wear eye protection when driving spring pins, as pins can eject unexpectedly if the hole is misaligned. Removal is performed by driving the pin through with a punch of matching diameter or extracting with a pin extractor.
