Holo-krome 08132 Shoulder Screw 3/4 in Alloy Steel Hex Socket

Product Description

The HOLO-KROME 08132 is a hex socket shoulder screw machined from grade 8 alloy steel with an uncoated finish. The shoulder measures 0.75 inches in diameter and 2.25 inches in length, providing the precise bearing surface that makes shoulder screws the right choice for pivot points, linkages, and guided-motion assemblies. The threaded end is 5/8-11 UNC with a 0.875-inch thread length. The rounded head measures 1 inch in diameter and 0.5 inches in height, accepting a 3/8-inch hex key. Overall length is 3.625 inches. Manufactured to ASME B18.3 and ASME B1.1 standards, this fastener is used by maintenance technicians, millwrights, and machine builders in demanding industrial applications.

This shoulder screw fits applications where a hardened, close-tolerance cylindrical shoulder is needed to act as a shaft, guide pin, or pivot. Common uses include die sets, jigs and fixtures, conveyor components, robotic assemblies, and hydraulic linkages. The uncoated alloy steel construction suits dry or lightly lubricated environments where dimensional precision is the priority. Each unit is sold individually, making it straightforward to order exact quantities for repair or new assembly work.

Key Features

• Grade 8 alloy steel construction for high shear strength and hardness
• 0.75-inch shoulder diameter with 2.25-inch shoulder length for precision fit in bored holes
• 5/8-11 UNC thread with 0.875-inch thread length meets ASME B1.1
• 3/8-inch hex socket drive compatible with standard hex keys and bit drivers
• Rounded head at 1 inch diameter and 0.5 inches height sits flush or proud as needed
• Meets ASME B18.3 dimensional standards for shoulder screw geometry

Compatibility

Designed as an OEM-style replacement or original-build fastener for any application requiring a 3/4-inch diameter shoulder screw with a 5/8-11 UNC threaded end in grade 8 alloy steel.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or mechanical assemblers using a 3/8-inch hex key or socket driver. Ensure the mating bore is machined to the correct tolerance for a 0.75-inch shoulder before installation. Do not exceed the fastener torque capacity of the threaded joint by over-driving. Follow applicable ASME or facility maintenance standards for fastener installation in load-bearing assemblies.
