Value Collection 015165PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 015165PR is a hex socket cap screw designed for secure mechanical fastening in demanding applications. It features a 1/4-20 UNC thread, a 2-1/2 inch length under head, and a 3/16 inch hex drive socket. Manufactured from alloy steel with a black oxide finish coating, this screw delivers high tensile strength and moderate corrosion resistance. It is partially threaded, which allows for proper clamping force when joining two components. Licensed machinists, millwrights, and maintenance mechanics commonly specify this fastener for machine assembly and fixture work.

This screw is suited for general industrial and mechanical assembly applications where a high-strength, internally driven cap screw is required. The hex socket drive allows use in recessed or tight-clearance installations where a standard hex head wrench cannot access. The black oxide finish provides a clean appearance and light surface protection, making it appropriate for indoor mechanical assemblies, tooling fixtures, machine guards, and equipment frames in both light industrial and commercial maintenance settings.

Key Features

• 1/4-20 UNC thread form for broad compatibility with standard inch-series tapped holes
• 2-1/2 inch length under head with partial threading for secure clamping
• 3/16 inch hex socket drive for use with standard Allen keys and hex bit drivers
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish coating for light corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 1/4-20 UNC partially threaded hex socket cap screw with a 2-1/2 inch length under head.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance mechanics using a 3/16 inch hex key or Allen driver. Always verify the receiving tapped hole depth and thread condition before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Torque to the value specified in the applicable equipment or assembly documentation.
