Holo-krome 08110 Shoulder Screw 5/8 in Alloy Steel Hex Socket

Product Description

The HOLO-KROME 08110 is a hex socket shoulder screw machined from Grade 8 alloy steel with an uncoated finish. The shoulder measures 5/8 inches in diameter and 2-1/2 inches in length, providing a precise bearing surface for pivoting, guiding, or locating components in mechanical assemblies. The threaded section is 1/2-13 UNC with a 3/4-inch thread length, and the rounded head measures 7/8 inches in diameter and 3/8 inches in height. Drive engagement is through a 5/16-inch hex socket. Overall length is 3-5/8 inches. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers wherever a hardened shoulder is required to serve as a shaft, pivot, or guide pin.

This shoulder screw is suited for use in jigs, fixtures, dies, linkages, and precision mechanical assemblies across industrial and manufacturing applications. The 5/8-inch shoulder diameter and Grade 8 alloy steel construction make it appropriate for moderate-to-high load pivoting and guiding applications in both light production equipment and heavy-duty fixtures. It conforms to ASME B18.3 and ASME B1.1 standards, making it a direct fit for applications where dimensional and strength compliance is required.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding mechanical applications
• 5/8-inch precision shoulder diameter provides an accurate bearing and locating surface
• 1/2-13 UNC thread with 3/4-inch thread length for secure fastening engagement
• 5/16-inch hex socket drive for use with standard Allen keys and hex bit drivers
• Uncoated finish maintains tight dimensional tolerances on the shoulder OD
• Meets ASME B18.3 and ASME B1.1 standards for dimensional and thread compliance

Compatibility

Designed as an OEM-style replacement or direct-use shoulder screw for mechanical assemblies, fixtures, and tooling that require a 5/8-inch shoulder diameter, 1/2-13 UNC thread, and ASME B18.3-compliant hex socket shoulder screw.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/16-inch hex key or socket bit driver. Ensure the mating bore is machined to the appropriate tolerance for the 5/8-inch shoulder to achieve the intended fit class. De-energize and lock out any equipment before replacing shoulder screws in live assemblies. Do not exceed the designed load rating for the thread size and material grade when torquing the fastener into the receiving thread.
