Value Collection R57600644 Shoulder Screw 3/4 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600644 is a shoulder screw machined from 18-8 stainless steel with an uncoated finish. It features a 0.75-inch shoulder diameter and a 1.25-inch shoulder length, making it suitable for applications that require a precision shaft or pivot point. The threaded portion is cut to a 5/8-11 UNC thread standard, and the head accepts a 3/8-inch hex socket drive. With a head diameter of 1 inch and a head height of 0.5 inches, this fastener is well-suited for mechanical assemblies where controlled bearing fit and corrosion resistance are required. Installation is performed by machinists, millwrights, and maintenance technicians.

This shoulder screw is used in mechanical linkages, jigs, fixtures, and rotating or sliding assemblies where the shoulder acts as a bearing surface or pivot pin. The 18-8 stainless steel construction provides resistance to corrosion in moderate chemical and moisture environments, making it appropriate for both indoor industrial and light washdown applications. It is sold individually and is suitable for OEM equipment builds, repair, and prototype fabrication work.

Key Features

• 0.75-inch shoulder diameter provides a precision bearing or pivot surface
• 1.25-inch shoulder length accommodates standard bearing widths and assembly tolerances
• 5/8-11 UNC thread for positive clamping engagement
• 18-8 stainless steel construction resists corrosion in moisture-prone environments
• 3/8-inch hex socket drive for torque application with standard socket tooling
• Uncoated finish maintains dimensional accuracy at the shoulder surface

Compatibility

Designed as an OEM-style replacement or direct-fit shoulder screw for mechanical assemblies requiring a 3/4-inch shoulder diameter, 5/8-11 UNC thread, and hex socket drive in 18-8 stainless steel.

Installation Notes

This fastener is installed by machinists, maintenance technicians, or millwrights using a 3/8-inch hex socket or Allen key. Ensure the mating bore is sized to match the 0.75-inch shoulder diameter for proper bearing fit before installation. Clean threads and inspect the mating assembly for damage prior to fastening. Do not use impact tools that may gall stainless threads; apply appropriate anti-seize compound if galling is a concern.
