Value Collection 33428 Low Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 33428 is a low socket cap screw designed for applications where standard socket cap head height creates clearance problems. Manufactured from alloy steel with a black oxide finish, this fastener features a 3/8-16 UNC thread and a length of 1-1/4 inches measured under the head. The 3/16-inch hex socket drive accepts a standard Allen key for installation and removal in confined spaces. Fully threaded along its entire length, the 33428 is suited for mechanical assemblies, fixtures, and tooling applications where a low-profile clamping fastener is required. This package contains 50 pieces.

Low socket cap screws like the 33428 are commonly used in machine tool setups, jigs, fixtures, and industrial equipment where head clearance is limited and a standard socket head cap screw would interfere with adjacent components. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision or optical environments. This fastener is appropriate for general industrial, manufacturing, and maintenance applications where inch-series alloy steel fasteners are specified.

Key Features

• Low socket cap head profile reduces clearance requirements compared to standard socket head cap screws
• Alloy steel construction provides high tensile strength for demanding clamping applications
• Black oxide finish offers mild corrosion resistance and a non-reflective surface
• Fully threaded along the entire shank length for maximum thread engagement
• 3/16-inch hex socket drive works with standard Allen keys and hex bit drivers
• Meets ASME/ANSI B18.8 fastener standard for consistent dimensional conformance

Compatibility

Designed as an OEM-style replacement or standard supply fastener for inch-series threaded assemblies requiring a 3/8-16 UNC low socket cap screw with a 1-1/4-inch under-head length.

Installation Notes

Install using a 3/16-inch hex key or Allen bit driver. Ensure mating threads are clean and free of debris before driving. Follow applicable torque specifications for the joint material and application per engineering documentation. De-energize and lock out any equipment before servicing assemblies that include these fasteners.
