Holo-krome 08094 Shoulder Screw 1/2 in Alloy Steel Hex Socket

Product Description

The HOLO-KROME 08094 is a Grade 8 alloy steel shoulder screw with a 0.5-inch shoulder diameter and a 4-inch shoulder length. The hex socket drive accepts a 1/4-inch hex key for installation and removal. The threaded section is 3/8-16 UNC with a 0.625-inch thread length, giving a measured overall length of 4.937 inches. The rounded head measures 0.75 inches in diameter and 0.3125 inches in height. This screw is manufactured to ASME B1.1 and ASME B18.3 standards, making it suitable for precision mechanical assemblies, jigs, fixtures, and linkage applications where a hardened, close-tolerance pivot or guide pin is required.

Shoulder screws of this configuration are used in industrial machinery, tooling, and fabrication setups where a controlled-diameter body is needed to serve as a bearing surface, pivot point, or spacer. The 0.5-inch shoulder diameter and 4-inch shoulder length accommodate applications requiring a longer precision pin. Machinists, millwrights, and tool-and-die professionals typically specify this fastener when assembling fixtures, die sets, or mechanical linkages that require consistent rotational or sliding fit clearances.

Key Features

• Grade 8 alloy steel construction for high tensile strength and durability
• 0.5-inch shoulder diameter with 4-inch shoulder length for extended pivot and guide applications
• 3/8-16 UNC thread with 0.625-inch thread length, conforming to ASME B1.1
• 1/4-inch hex socket drive for precise installation torque control
• Manufactured to ASME B18.3 dimensional standards
• Uncoated finish suitable for use with standard lubrication or coating applied in the field

Compatibility

Designed as an OEM-style and aftermarket replacement shoulder screw for industrial machinery, tooling fixtures, and mechanical assemblies requiring a 0.5-inch shoulder diameter and 3/8-16 threaded shank.

Installation Notes

Installation requires a 1/4-inch hex key or hex socket driver. Ensure the mating bore diameter matches the 0.5-inch shoulder for the intended fit class before installation. Torque the threaded shank into a properly tapped or threaded insert without applying force to the shoulder body. Always inspect threads and the shoulder surface for damage before reuse in a precision assembly.
