Value Collection 011277P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011277P is a hex socket cap screw designed for applications requiring a high-strength, compact fastener with an internal drive. Manufactured from alloy steel with a black oxide finish, this screw measures 4 inches in length under the head and uses a 5/16-inch hex drive. It carries a 3/8-16 UNC thread and is partially threaded along its shank. The black oxide coating provides moderate corrosion resistance and reduces light reflection in finished assemblies. Licensed trades and industrial maintenance crews install this fastener in machine components, brackets, tooling fixtures, and structural subassemblies where a flush or recessed drive is required.

This screw is suited for general industrial, mechanical, and maintenance applications where a 3/8-16 UNC thread pattern is specified. Its partially threaded shank allows for clamping force to develop between mating parts rather than threading through the full grip length. Typical install scenarios include equipment fabrication, machine tool assembly, and structural fastening in ferrous material applications. The alloy steel construction provides the tensile strength needed for medium-to-high load fastening tasks encountered in shop and field environments.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• 4-inch length under head accommodates thicker material stacks or longer grip lengths
• Partially threaded shank provides clamping action across unthreaded grip zone
• 5/16-inch hex socket drive accepts standard Allen or hex-key tools
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and a low-glare surface

Compatibility

Designed as an OEM-style and general-use replacement or primary fastener for any application specifying a 3/8-16 UNC hex socket cap screw with a 4-inch length under head. Meets ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen driver; use a torque wrench rated for the fastener grade when specified by the equipment manufacturer. Ensure the receiving tapped hole is clean and free of debris before installation. Follow applicable mechanical and structural codes for the assembly type. Do not exceed the rated tensile load for the fastener grade as established by ASTM A574.
