Value Collection MP72154 Hex Socket Cap Screw 3/8-16 Unc 25 Pack

Product Description

The VALUE COLLECTION MP72154 is a 3/8-16 UNC hex socket cap screw designed for high-strength mechanical fastening applications. Manufactured from alloy steel with a black oxide finish, this fastener meets ASME B18.3 and ASTM A574 standards, making it suitable for demanding industrial and mechanical assemblies. The screw features a 3/4 inch length under head, is fully threaded, and accepts a 5/16 inch hex drive. Black oxide coating provides a degree of corrosion resistance and reduces light reflection in finished assemblies. This package contains 25 pieces.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical panel fabrication, plumbing fixture mounting, and general mechanical installations. The 3/8-16 UNC thread is one of the most common coarse-thread sizes in North American hardware, making this screw a go-to choice for maintenance technicians, millwrights, and field service professionals who need a reliable, standards-compliant socket cap screw in bulk quantities.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded along the 3/4 inch length under head for maximum thread engagement
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and a low-profile appearance
• 5/16 inch hex socket drive for use with standard Allen wrenches or hex bit drivers
• Conforms to ASME B18.3 dimensional standards
• Sold in a 25-piece package for jobsite or shop stocking

Compatibility

Designed as a standard ASME B18.3 and ASTM A574 compliant hex socket cap screw suitable for any 3/8-16 UNC tapped hole application requiring a fully threaded alloy steel fastener with a black oxide finish.

Installation Notes

Installation should be performed with a correctly sized 5/16 inch hex key or socket bit to avoid rounding the drive recess. Ensure mating threads are clean and free of debris before driving. Follow applicable torque specifications from your assembly drawing or relevant mechanical code for 3/8-16 alloy steel fasteners. Black oxide is a mild finish and is not a substitute for corrosion-rated hardware in wet or outdoor environments.
