Value Collection R57001070 Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION R57001070 is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, fabrication work, and equipment maintenance. It features a 7/16-20 UNF thread — a fine-pitch unified thread that provides strong clamping force and vibration resistance. The screw measures 2 inches in length under the head and accepts a 3/8 inch hex drive key for installation. Constructed from 18-8 stainless steel with a bright uncoated finish, it delivers solid corrosion resistance in wet, outdoor, and chemically exposed environments. Machinists, pipefitters, millwrights, and general maintenance technicians commonly use this fastener type across a wide range of applications.

This hex socket cap screw suits residential and commercial mechanical work wherever a fine-thread fastener is required. Common install scenarios include equipment frames, brackets, manifolds, pump housings, and fluid system components. The fine UNF thread pitch makes it well suited for applications requiring precise torque control or repeated disassembly. The recessed hex socket drive allows installation in tight or recessed clearances where a standard hex head wrench cannot reach.

Key Features

• 7/16-20 UNF fine-thread pitch for high clamping force and vibration resistance
• 2 inch length under head for moderate fastening depth
• 3/8 inch hex socket drive for use with standard Allen keys or socket drive tools
• 18-8 stainless steel construction with bright uncoated finish for corrosion resistance
• Recessed drive head allows access in confined or counter-bored installations

Compatibility

Designed as a standard UNF hex socket cap screw for use in any application requiring a 7/16-20 fine-thread fastener with a 3/8 inch hex drive and 2 inch length under head.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or trade professionals using a 3/8 inch hex key or Allen socket drive. Verify that the mating threaded hole is clean and properly tapped to 7/16-20 UNF before installation. Apply thread lubricant or anti-seize compound as required by the application to prevent galling on stainless steel threads. Follow applicable torque specifications for the material and joint type per engineering standards for the assembly.
