Value Collection 711018PR Shoulder Screw 1/4 in 2 in 10-24

Product Description

The VALUE COLLECTION 711018PR is a 4140 alloy steel shoulder screw designed for precision fastening applications requiring a ground cylindrical shoulder as a bearing or pivot surface. The shoulder measures 0.25 inches in diameter and 2 inches in length, providing a smooth, accurate shank between the head and the threaded portion. The thread is 10-24 UNC. Drive is a 1/8 inch hex socket, accepting a standard Allen key or hex bit driver. The head diameter is 0.375 inches and the head height is 0.1875 inches. This screw ships uncoated and meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards. Installed by machinists, maintenance technicians, and assembly professionals across industrial, mechanical, and equipment manufacturing environments.

Shoulder screws of this type are commonly used as pivot pins, guide shafts, die-set components, and spacers in machinery, fixtures, tooling, and precision assemblies. The 4140 alloy steel construction provides high tensile strength and wear resistance suitable for dynamic loads and repeated motion applications. This screw is appropriate for use in industrial equipment, pneumatic and hydraulic components, jigs and fixtures, and general mechanical assemblies where a precise shoulder diameter is required for fit and function. This item has a minimum order quantity of 25 units.

Key Features

• Shoulder diameter: 0.25 inches for precision fit in bored holes and bushings
• Shoulder length: 2 inches providing ample bearing surface or pivot travel
• 4140 alloy steel construction for high tensile strength and wear resistance
• 10-24 UNC thread for positive, reliable engagement
• 1/8 inch hex socket drive for Allen key or hex bit installation
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards
• Uncoated finish — compatible with secondary coating or plating processes

Compatibility

Designed as a standard ANSI B18.3 shoulder screw for general industrial and mechanical assembly applications requiring a 0.25 inch shoulder diameter and 10-24 UNC thread. Confirm bore diameter and thread depth in the mating component before installation.

Installation Notes

Installation is performed by machinists, maintenance technicians, or assembly personnel using a 1/8 inch hex key or hex socket driver. Ensure the receiving bore is sized to the shoulder diameter tolerance per ANSI B18.3 specifications before installation. Do not overtighten — apply only the torque required to seat the head flush against the mating surface without deforming the thread. De-energize and lock out any equipment before replacing shoulder screws in live machinery.
