Value Collection -40835-4 Shoulder Screw 1/2x5 in 3/8-16

Product Description

The VALUE COLLECTION -40835-4 is an alloy steel shoulder screw with a 0.5-inch shoulder diameter and a 5-inch shoulder length. It features a 3/8-16 UNC thread and a hex socket drive sized at 1/4 inch, making it compatible with standard hex keys and socket drivers. Built to Material Grade 8 alloy steel with an uncoated finish, this fastener provides high tensile strength suited to precision mechanical assemblies. The head measures 3/4 inch in diameter and 5/16 inch in height. This screw meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards. Sold in a package quantity of 10.

Shoulder screws of this type are used across industrial, mechanical, and tooling applications where a precise pivot point, guide pin, or bearing journal is required. The 5-inch shoulder length suits linkage assemblies, fixture plates, jig components, and similar setups where a defined unthreaded shaft must extend through a bore before engaging the thread. Machinists, maintenance technicians, and industrial assembly professionals are the typical installers.

Key Features

• 0.5-inch shoulder diameter for consistent bore fit in precision applications
• 5-inch shoulder length provides extended pivot or guide surface
• 3/8-16 UNC thread for secure clamping engagement
• Grade 8 alloy steel construction for high tensile and shear strength
• 1/4-inch hex socket drive compatible with standard hex keys
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw for use in precision fixtures, jigs, mechanical linkages, and assemblies requiring a 1/2-inch shoulder diameter, 5-inch shoulder length, and 3/8-16 UNC thread engagement.

Installation Notes

Installation is performed using a 1/4-inch hex key or socket driver. Ensure the receiving bore is sized to match the 0.5-inch shoulder diameter for proper fit and alignment. Thread engagement should be verified against the receiving material to confirm adequate clamping depth. Follow applicable ASME fastener standards and torque the screw to values appropriate for Grade 8 alloy steel in the specific joint configuration.
