Value Collection MP33636 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MP33636 is a hex socket cap screw designed for secure fastening in applications requiring precise torque control and a flush, low-profile head. Threaded 3/8-16 UNC and measuring 1-1/2 inches in length under the head, this fastener is fully threaded along its entire shaft. Drive engagement is achieved with a 5/16-inch hex key. Constructed from alloy steel with a black oxide coating, the MP33636 delivers solid mechanical strength and moderate corrosion resistance. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards, making it a reliable choice for structural and mechanical assembly work across trade and industrial settings.

This socket cap screw is suited for general mechanical assemblies, equipment maintenance, and fabrication tasks where a standard hex head is not practical due to clearance constraints. The internal hex drive allows fastening in recessed or confined spaces. It is commonly used by millwrights, pipefitters, HVAC equipment assemblers, and general maintenance mechanics working with machine components, brackets, enclosures, and structural steel connections.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard inch-series tapped holes
• Fully threaded shaft at 1-1/2 inches length under head for maximum thread engagement
• 5/16-inch hex socket drive for use with standard Allen keys or hex-bit sockets
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any application requiring an ASME/ANSI B18.3-compliant fastener in a 3/8-inch tapped hole.

Installation Notes

Installation requires a 5/16-inch hex key or Allen-bit socket driver. Verify that the mating tapped hole is clean, undamaged, and cut to 3/8-16 UNC specification before driving the fastener. Power down or de-energize any equipment before accessing fastener locations on live machinery. Apply thread lubricant or anti-seize compound only as appropriate for the assembly material and environment.
