Value Collection 711162BR Shoulder Screw 1in 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711162BR is a hex socket shoulder screw machined from 4140 alloy steel, designed for precision fastening applications in industrial, mechanical, and tooling assemblies. The shoulder measures 1 inch in diameter and 2-1/4 inches in length, providing a close-tolerance bearing surface for rotating or sliding components. The 3/4-10 UNC threaded section anchors the fastener securely into tapped holes. Drive engagement is via a 1/2 inch hex socket. This fastener is uncoated and shipped individually. Machinists, tool-and-die professionals, and maintenance technicians typically install this type of screw.

Shoulder screws of this type are used in jigs, fixtures, die sets, and linkage assemblies where a precision cylindrical surface is needed to guide or pivot a mating component. The 1 inch shoulder diameter and 2-1/4 inch shoulder length make this fastener suitable for moderate-load pivoting, alignment, or guided-motion applications in both production and maintenance settings. The 4140 alloy steel construction provides the strength and wear resistance demanded in shop-floor and heavy-duty manufacturing environments.

Key Features

• 1 inch shoulder diameter with 1.0000 inch decimal precision for close-tolerance fits
• 2-1/4 inch shoulder length provides ample bearing surface for guided or pivoting components
• 3/4-10 UNC thread standard per ANSI B18.3 and ASME/ANSI B18.3
• 4140 alloy steel construction meets ASTM A574 requirements for high-strength socket screws
• 1/2 inch hex socket drive for standard Allen wrench or socket tool installation
• Uncoated finish — suitable for applications where coating buildup on the shoulder is not acceptable

Compatibility

Designed as a standard shoulder screw for use in jigs, fixtures, die sets, and mechanical linkages requiring a 1 inch diameter precision shoulder and 3/4-10 UNC thread engagement.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/2 inch hex key or socket driver. Ensure the mating tapped hole is clean, properly sized for 3/4-10 UNC thread, and free of debris before installation. Do not overtighten; apply torque appropriate to 4140 alloy steel fasteners of this thread class per applicable engineering specifications. The shoulder must seat flush against its mating surface to function as a precision bearing or guide.
