Holo-krome 08093 Shoulder Screw 1/2 in Alloy Steel Hex Socket

Product Description

The HOLO-KROME 08093 is a Grade 8 alloy steel shoulder screw with a 1/2-inch shoulder diameter and a 3-3/4-inch shoulder length. The threaded end is sized 3/8-16 UNC with a 5/8-inch thread length, and the fastener is driven by a 1/4-inch hex socket. The rounded head measures 3/4 inch in diameter and 5/16 inch in height. With an uncoated finish and full conformance to ASME B18.3 and ASME B1.1, this shoulder screw is suited for precision mechanical assemblies where a hardened, close-tolerance shaft is required to guide, pivot, or constrain a mating component.

Shoulder screws of this type are used in jigs, fixtures, dies, and machine assemblies across industrial and manufacturing environments. The 1/2-inch shoulder acts as a precision bearing surface or pivot point for bushings, rollers, linkages, and similar components. The Grade 8 alloy steel construction provides the tensile strength needed in high-load or high-cycle applications. Machinists, toolmakers, and maintenance mechanics are the typical installers in shop and field settings.

Key Features

• 1/2-inch shoulder diameter with a 3-3/4-inch shoulder length for precision fit in bored or reamed holes
• 3/8-16 UNC threaded end with 5/8-inch thread length for secure clamping into tapped bores
• Grade 8 alloy steel construction for high tensile strength and wear resistance
• 1/4-inch hex socket drive for controlled torque with a standard Allen wrench or hex key
• Uncoated finish suitable for use as-supplied or for subsequent plating or coating processes
• Conforms to ASME B18.3 and ASME B1.1 dimensional and thread standards

Compatibility

Designed as a standard ASME B18.3 shoulder screw for use in any application requiring a 1/2-inch precision shoulder, 3/8-16 tapped receiving hole, and a hex socket drive head.

Installation Notes

Shoulder screws are typically installed by machinists or maintenance mechanics using a 1/4-inch hex key or Allen driver. Ensure the receiving bore matches the shoulder diameter tolerance specified by ASME B18.3 before installation. De-energize or lock out any machine before replacing or installing shoulder screws in live assemblies. Do not use an impact driver, as this may damage the hex socket or over-torque the threaded portion.
