Value Collection KP25100 Hex Socket Cap Screw 1/4-20 Unc 25pk

Product Description

The VALUE COLLECTION KP25100 is a hex socket cap screw designed for secure, high-strength fastening in mechanical, structural, and industrial assemblies. Sized at 1/4-20 UNC with a 1-3/8 inch length under head and a 3/16 inch hex drive, this fully threaded fastener delivers reliable clamping force across a wide range of applications. Manufactured from alloy steel and finished with a black oxide coating, it offers solid corrosion resistance and a clean appearance. Sold in a pack of 25, this screw is a practical stock item for maintenance, fabrication, and equipment repair work.

This socket cap screw is suited for residential and commercial mechanical applications where a low-profile, high-torque fastener is required. The 1/4-20 UNC thread pattern is one of the most common unified coarse thread standards in North American mechanical work, making this screw a go-to for equipment panels, jigs, fixtures, motor mounts, and general machine assembly. The black oxide finish reduces light reflection and provides mild surface protection in dry or low-humidity environments. Technicians and fabricators across HVAC, electrical, and mechanical trades will find this screw a dependable choice for routine fastening tasks.
