Holo-krome 08096 Shoulder Screw 1/2 in Alloy Steel Hex Socket

Product Description

The HOLO-KROME 08096 is a Grade 8 alloy steel shoulder screw designed for precision fastening applications where a hardened, close-tolerance shoulder is required. The screw features a 0.5-inch shoulder diameter and a 4.5-inch shoulder length, providing a smooth bearing surface for rotating or sliding components such as linkages, cams, and pivot assemblies. The threaded portion is 3/8-16 UNC with a 0.625-inch thread length. Drive engagement is via a 0.25-inch hex socket, and the head measures 0.75 inches in diameter and 0.3125 inches in height. Finish is uncoated. This fastener is installed by machinists, maintenance technicians, and assembly professionals in industrial and mechanical applications.

The HOLO-KROME 08096 is suited for use in mechanical assemblies requiring a fixed-diameter shaft section for bearing bores, bushings, or similar close-fit interfaces. Typical applications include jigs and fixtures, conveyor components, cam followers, and general industrial machinery. The Grade 8 alloy steel construction supports high shear and tensile loads. This screw is sold individually and is appropriate for both OEM assembly and MRO replacement use.

Key Features

• 0.5-inch shoulder diameter with 4.5-inch shoulder length for extended bearing surface
• Grade 8 alloy steel construction for high-strength fastening under shear and tensile loads
• 3/8-16 UNC threaded end with 0.625-inch thread length conforming to ASME B1.1
• 0.25-inch hex socket drive for secure torque application with standard Allen keys
• Uncoated finish — compatible with environments where coating interference with bore tolerances is a concern
• Meets ASME B18.3 dimensional standards for socket head cap and shoulder screws

Compatibility

Designed as an OEM-style and MRO replacement shoulder screw for industrial mechanical assemblies requiring a 0.5-inch diameter precision shoulder and 3/8-16 threaded end per ASME B18.3.

Installation Notes

Shoulder screws of this type are installed by qualified machinists or maintenance technicians using a hex key or Allen driver sized to the 0.25-inch socket. Ensure the mating bore is reamed or drilled to the appropriate close-tolerance fit for the 0.5-inch shoulder before installation. Power down and de-energize any equipment before servicing fasteners in operational assemblies. Do not substitute this screw with a standard cap screw where a precision shoulder bore interface is specified.
