Value Collection 015169PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 015169PR is a hex socket cap screw designed for high-strength mechanical fastening in industrial, commercial, and trade applications. Sized at 1/4-20 UNC with a 3-inch length under head, this screw features a 3/16-inch hex drive socket and is partially threaded along the shank. Manufactured from alloy steel with a black oxide coating, it delivers corrosion resistance and hardness suited to demanding service environments. Licensed contractors, millwrights, and maintenance technicians use this fastener when a flush or recessed socket drive is required over a standard hex head.

This screw is suited for use in machinery assembly, structural brackets, equipment mounting, and maintenance repair work where a compact drive profile is needed. The 1/4-20 UNC thread form is a widely used coarse-thread standard found in metal fabrication, HVAC equipment panels, pump housings, and general mechanical assemblies. The black oxide finish reduces surface reflectivity and provides mild corrosion protection in dry or lightly oiled environments. Sold in a minimum order quantity of 10 pieces per order.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility in standard threaded assemblies
• 3-inch length under head suits medium-depth fastening applications
• 3/16-inch hex socket drive accommodates standard Allen or hex key tooling
• Partially threaded shank provides clamping force and shear resistance
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish offers mild corrosion protection and low surface reflectivity

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any threaded assembly requiring an ASME/ANSI B18.3 or ASTM A574 compliant fastener with a 3/16-inch hex drive socket.

Installation Notes

Installation typically requires a 3/16-inch hex key or Allen driver; use a torque wrench rated for the fastener size to avoid thread stripping in tapped holes. Ensure mating threads are clean and free of debris before installation. Follow applicable mechanical or structural codes for the specific assembly. Power down or de-energize any equipment before fastening work on live mechanical or electrical enclosures.
