Value Collection -33650-1 Hex Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION -33650-1 is a hex socket cap screw designed for mechanical fastening applications requiring a recessed drive interface. Sized at 7/16-14 UNC thread with a 2-inch length under head, this fastener is partially threaded and accepts a 3/8-inch hex (Allen) drive. Constructed from alloy steel with a black oxide coating, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for moderate-strength bolted joints in industrial and mechanical assemblies. The black oxide finish provides light corrosion resistance and reduces surface reflectivity.

This cap screw is used in general mechanical assembly, machine building, tooling fixtures, and equipment maintenance. Partially threaded shanks are specified when a smooth shank section is needed for bearing surfaces or close-tolerance bores. The 7/16-14 UNC coarse thread pitch is common in steel-to-steel applications where quick assembly and resistance to cross-threading are priorities. Suitable for use by machinists, millwrights, and maintenance technicians in light industrial and commercial settings.

Key Features

• 7/16-14 UNC coarse thread for reliable steel-to-steel engagement
• 2-inch length under head with partial threading for smooth shank clearance
• 3/8-inch hex socket drive compatible with standard Allen keys and hex-bit drivers
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide coating provides light surface corrosion resistance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in tapped holes accepting 7/16-14 UNC threads in industrial machinery, fixtures, and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a calibrated 3/8-inch hex key or hex-bit driver. Verify thread engagement depth and hole alignment before torquing. De-energize and lock out equipment before replacing fasteners in live assemblies. Do not use impact drivers without a torque-limiting attachment, as overtorque can compromise thread integrity in the base material.
