Value Collection MP72124 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION MP72124 is a fully threaded hex socket cap screw designed for secure fastening in mechanical assemblies, fixtures, and equipment. It features a 5/16-18 UNC thread size and a 3/4-inch length under head, driven by a 1/4-inch hex socket drive. Constructed from alloy steel with a black oxide coating, this screw delivers solid tensile strength and basic corrosion resistance in a compact form factor. Sold in a pack of 50, it suits applications where consistent, repeatable fastener performance is required across multiple connection points.

This screw is appropriate for use in light industrial, mechanical, and equipment assembly contexts where a recessed drive fastener is preferred for torque control and flush or countersunk installation. The 5/16-18 UNC thread is a common coarse-thread standard found across a wide range of fabricated components, jigs, enclosures, and structural brackets. Installers working in HVAC equipment assembly, electrical enclosure builds, or general mechanical maintenance will find this a practical fastener choice for high-volume work.

Key Features

• 5/16-18 UNC fully threaded profile for maximum thread engagement across the full shank length
• 3/4-inch length under head for standard-depth fastening applications
• 1/4-inch hex socket drive for use with common hex keys and socket drivers
• Alloy steel construction meets ASME B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Pack of 50 supports production, maintenance, and service work requiring multiple fasteners

Compatibility

Designed as a standard-dimension hex socket cap screw suitable for any application calling for a 5/16-18 UNC coarse-thread fastener with a 3/4-inch length under head and 1/4-inch hex drive.

Installation Notes

Installation should be performed with the appropriate 1/4-inch hex key or socket driver to avoid rounding the drive recess. Ensure mating threads are clean and free of debris before assembly. Follow applicable torque specifications for 5/16-18 alloy steel fasteners as required by the equipment manufacturer or relevant industry standards. Wear appropriate hand protection when handling fasteners in bulk quantities.
