Value Collection MP72098 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION MP72098 is a 1/4-20 UNC hex socket cap screw designed for secure mechanical fastening in industrial, commercial, and trade applications. The screw measures 7/8 inches in length under the head and is fully threaded, allowing full thread engagement across the entire shank. Drive interface is a 3/16 inch internal hex (Allen) socket. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and basic corrosion resistance suited for indoor and controlled-environment installations. Sold in a package of 50. Meets ASME B18.3 and ASTM A574 standards.

This socket cap screw is used in a wide range of mechanical assemblies where a low-profile, high-strength fastener is required. Typical applications include equipment mounting, machine frames, HVAC unit assemblies, electrical enclosures, and general mechanical fabrication. The black oxide coating makes it appropriate for light-corrosion-resistant interior applications. The 1/4-20 UNC thread pattern is one of the most common inch-series thread forms, making this screw broadly compatible with standard tapped holes in that size.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes
• 7/8 inch length under head, fully threaded along the entire shank
• 3/16 inch internal hex drive for use with standard Allen or hex keys
• Alloy steel construction meets ASTM A574 for high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME B18.3 dimensional standards
• Sold as a package of 50 pieces

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for any application requiring an ASME B18.3 compliant fastener in that thread size and length.

Installation Notes

Installation requires a 3/16 inch hex key or Allen wrench; use of a calibrated torque wrench is recommended where fastener preload is specified by the equipment manufacturer. Ensure mating threads are clean and free of debris before installation. Follow applicable mechanical codes and equipment service manuals for proper torque values. Do not reuse fasteners that show signs of thread damage or deformation.
