Value Collection KP25099 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION KP25099 is a hex socket cap screw designed for fastening applications requiring a recessed drive interface and reliable clamping strength. The screw features a 1/4-20 UNC thread size and measures 1-1/8 inches in length under the head. Drive engagement is through a 3/16-inch hex (Allen) socket. Constructed from alloy steel with a black oxide finish coating, this fastener delivers solid corrosion resistance and hardness suitable for machine assembly, tooling fixtures, and mechanical subassemblies. The thread is fully threaded along the shank. Licensed tradespeople and maintenance mechanics install this type of fastener across industrial and commercial applications.

This screw is suited for use in machine frames, brackets, jigs, and mechanical assemblies where a flush or recessed fastener head is required. The 1/4-20 UNC thread pattern is one of the most common unified coarse-thread standards in North American fastener applications, making this screw broadly applicable in light to medium-duty mechanical assemblies. The black oxide coating reduces surface friction during installation and provides mild protection against oxidation in dry or minimally humid environments.

Key Features

• 1/4-20 UNC fully threaded shank for broad compatibility with standard tapped holes
• 3/16-inch hex socket drive for use with standard Allen wrenches or hex bits
• 1-1/8-inch length under head provides adequate grip length for typical bracket and frame applications
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 fastener standards
• Black oxide finish coating reduces galling and provides mild corrosion resistance

Compatibility

Designed as an OEM-style replacement or standard-use fastener for any application requiring a 1/4-20 UNC hex socket cap screw with a 1-1/8-inch length under head.

Installation Notes

Installation is performed using a 3/16-inch hex key or Allen-drive bit. Ensure the mating tapped hole is clean and free of debris before threading. Power down and de-energize any equipment before accessing fastener locations on live assemblies. Follow applicable mechanical and industrial codes for torque requirements based on joint material and application load.
