Value Collection 41020 Shoulder Screw 1in X 6in 3/4-10 Alloy Steel

Product Description

The VALUE COLLECTION 41020 is a heavy-duty shoulder screw machined from 4140 alloy steel and finished uncoated for a clean, dimensionally accurate surface. The shoulder measures 1 inch in diameter and 6 inches in length, providing a precise bearing or pivot surface in mechanical assemblies. Drive engagement is via a 1/2 inch hex socket, allowing high torque application without fastener damage. The head measures 1-5/16 inches in diameter and 5/8 inch in height. The threaded shank is sized 3/4-10 UNC. This fastener meets ANSI B18.3 and ASTM A574 standards and is used by machinists, millwrights, and maintenance technicians in industrial and mechanical applications.

This shoulder screw is suited for applications requiring a hardened, close-tolerance pin-like shank to serve as a shaft, pivot, or guide. Common uses include jigs and fixtures, linear motion assemblies, linkages, and machinery requiring a screw with a smooth unthreaded body section. The large hex socket drive and oversized head make it well-suited for high-clamp-load installations. This SKU is sold as a package quantity of 5 per order.

Key Features

• 4140 alloy steel construction for high strength and wear resistance
• 1 inch shoulder diameter and 6 inch shoulder length provide a true bearing surface
• 1/2 inch hex socket drive accepts standard hex keys and socket drive tools
• 3/4-10 UNC thread standard for broad tooling and hardware compatibility
• Uncoated finish maintains tight dimensional tolerances out of the box
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard ANSI B18.3 shoulder screw for use in industrial machinery, fixtures, and mechanical assemblies requiring a 1 inch diameter, 6 inch length uncoated alloy steel pivot or guide fastener with a 3/4-10 UNC threaded shank.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using a 1/2 inch hex key or hex socket driver. Ensure the mating bore is sized to the shoulder diameter tolerance before installation to achieve the intended fit. De-energize and lock out all machinery before fastener service in live equipment. Do not exceed the rated drive size when applying torque to avoid socket rounding.
