Value Collection 711094PR Shoulder Screw 1/2 in 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711094PR is a shoulder screw machined from 4140 alloy steel with an uncoated finish. It features a 1/2-inch shoulder diameter and a 3/8-inch shoulder length, paired with a 3/8-16 UNC threaded end. The hex socket drive accepts a 1/4-inch hex key for installation. With a 3/4-inch head diameter and a 5/16-inch head height, this fastener is built to handle precise locating, pivoting, and guiding applications in mechanical assemblies. Meets ANSI B18.3 and ASME/ANSI B18.3 standards, and is manufactured to ASTM A574 requirements. Licensed trades and mechanical assembly technicians install this type of fastener in production and maintenance environments.

This shoulder screw is suited for use in jigs, fixtures, linkages, and pivot assemblies where a precise, hardened bearing surface is required. The 4140 alloy steel construction provides the tensile strength needed in high-load or cyclic-stress applications. Common in industrial machinery, tooling, and mechanical sub-assemblies where alignment and controlled rotation are critical. This item is sold individually but is available in minimum order quantities of 10 units.

Key Features

• 1/2-inch shoulder diameter provides a precision bearing and locating surface
• 3/8-inch shoulder length suits compact pivot and guide applications
• 3/8-16 UNC threaded end for secure engagement in standard tapped holes
• 4140 alloy steel construction for high tensile strength and wear resistance
• 1/4-inch hex socket drive for controlled torque installation with a hex key
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for mechanical assemblies requiring a 1/2-inch shoulder diameter shoulder screw with a 3/8-16 UNC thread form.

Installation Notes

Install using a 1/4-inch hex key driver. De-energize and lock out any machine or assembly before replacing fasteners in live equipment, following applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity of the drive recess or the thread engagement length of the mating tapped hole. Thread engagement of at least one full shoulder-screw thread diameter is recommended practice for alloy steel fasteners in structural applications.
