Value Collection 015149PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 015149PR is a hex socket cap screw designed for secure mechanical fastening in demanding industrial and trade applications. Featuring a 1/4-20 UNC thread size and a 3/4-inch length under head, this fastener is fully threaded and driven with a 3/16-inch hex key. Constructed from alloy steel with a black oxide coating, it offers solid corrosion resistance and high tensile strength suitable for use in machine assembly, equipment mounting, and structural fastening tasks. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for precision and load-bearing applications.

This screw is used across a wide range of trade and industrial settings, including HVAC equipment assembly, mechanical rooms, pump and motor mounting, and general fabrication. The 1/4-20 UNC thread pattern is one of the most common coarse-thread standards in North American fastener applications, making this screw a practical stock item for service technicians and maintenance professionals. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies.
