Value Collection 711325BR Shoulder Screw 1x7 in 3/4-10 Alloy Steel

Product Description

The VALUE COLLECTION 711325BR is a heavy-duty shoulder screw machined from 4140 alloy steel with an uncoated finish. It features a 1-inch shoulder diameter and a 7-inch shoulder length, making it well-suited for applications that demand precise shaft positioning, pivoting, or bearing alignment. The fastener is driven by a 1/2-inch hex socket drive and uses a 3/4-10 UNC thread form. With a head diameter of 1-5/16 inches and a head height of 5/8 inch, it provides a robust bearing surface for clamping or locating work. Machinists, maintenance technicians, and mechanical assemblers working with industrial equipment and machinery are the primary installers of this component.

This shoulder screw is intended for general industrial and mechanical assembly applications where a hardened, accurately dimensioned shoulder is required to guide, pivot, or locate mating components. Typical use cases include fixture building, die and mold assemblies, pivot joints, linkage mechanisms, and precision jig construction. The 4140 alloy steel construction provides the tensile strength and hardness needed for demanding load-bearing environments in both shop and field settings.

Key Features

• 1-inch shoulder diameter with 7-inch shoulder length for long-reach positioning applications
• 4140 alloy steel construction for high tensile strength and wear resistance
• 3/4-10 UNC thread form for broad hardware compatibility
• 1/2-inch hex socket drive for high-torque installation with standard tooling
• Uncoated finish suitable for use as-is or with additional surface treatment
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw replacement or new-build fastener for industrial machinery, fixtures, dies, molds, and mechanical assemblies requiring a 1-inch diameter, 7-inch length shoulder with a 3/4-10 UNC threaded end.

Installation Notes

Installation is performed by qualified machinists or mechanical technicians using a 1/2-inch hex key or socket driver. Ensure mating bores are sized to the shoulder diameter tolerance before installation and that all moving or powered equipment is de-energized and locked out prior to fastener service. Refer to applicable ANSI and ASME standards for torque and thread engagement requirements appropriate to this fastener grade and size.
