Value Collection MP33646-1 Hex Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION MP33646-1 is a hex socket cap screw designed for mechanical fastening applications requiring a compact drive interface and high tensile strength. Manufactured from alloy steel with a black oxide finish, this fastener measures 1 inch in length under the head and features a 7/16-14 UNC thread form with full threading along the shank. The 3/8-inch hex drive allows engagement with standard Allen keys and hex bit drivers. Black oxide coating provides moderate corrosion resistance and reduces light reflection in finished assemblies. This screw conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for precision and structural fastening tasks.

This socket cap screw is used in general industrial, mechanical, and maintenance applications where a low-profile head and internal hex drive are preferred over external fastener heads. Typical installations include machinery housings, jigs, fixtures, brackets, and equipment panels. The 7/16-14 UNC coarse thread is well suited for use in steel, cast iron, and other ferrous base materials where thread cutting or engagement with standard tapped holes is required.

Key Features

• 7/16-14 UNC coarse thread for broad compatibility with standard tapped holes in ferrous materials
• 1-inch length under head with full threading along entire shank
• 3/8-inch internal hex drive accepts standard Allen keys and hex bit sockets
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides moderate corrosion resistance and low-glare appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard replacement or stock fastener for applications requiring a 7/16-14 UNC hex socket cap screw per ASME/ANSI B18.3 dimensional specifications.

Installation Notes

Installation is performed using a 3/8-inch hex key or Allen bit driver. Power down or de-energize any equipment before servicing fastened assemblies. Ensure mating threaded holes are clean, properly tapped to 7/16-14 UNC, and free of debris before installation. Do not exceed the rated torque range for ASTM A574 alloy steel socket cap screws as defined by the applicable engineering specification for the application.
