Value Collection MP33638 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION MP33638 is a hex socket cap screw engineered for secure fastening in mechanical, industrial, and trade applications. It features a 3/8-16 UNC thread size with 2 inches of length under the head and a 5/16-inch hex drive socket. The fastener is partially threaded and manufactured from alloy steel with a black oxide finish coating that provides moderate corrosion resistance and reduces surface glare. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it a recognized choice where dimensional and tensile consistency are required. Licensed tradespeople and maintenance professionals install these in equipment assemblies, brackets, and structural connections across HVAC, mechanical, and general trade environments.

This screw is suited for use in light to medium-duty fastening scenarios where a recessed hex drive is required for clearance or torque reasons. The partial threading allows for clamping force between joined materials without thread engagement all the way to the head. Applications include equipment panels, mounting brackets, mechanical assemblies, and maintenance repairs in residential and commercial settings.

Key Features

• 3/8-16 UNC thread size for standard inch-series fastening
• 2-inch length under head with partial threading for strong clamping grip
• 5/16-inch hex socket drive for use with standard hex keys and Allen drivers
• Alloy steel construction rated to ASTM A574 for reliable tensile strength
• Black oxide finish coating for mild corrosion resistance and low-glare appearance
• Conforms to ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM A574 compliant hex socket cap screw suitable for general mechanical and trade fastening applications requiring a 3/8-16 UNC thread.

Installation Notes

Install and remove using a calibrated hex key or Allen driver sized to 5/16 inch. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before replacing or installing fasteners on live machinery. Follow applicable mechanical and safety codes for the equipment type being serviced.
