Value Collection R57600566 Shoulder Screw 1/2 in 3/8-16 Ss

Product Description

The VALUE COLLECTION R57600566 is a hex socket shoulder screw machined from 18-8 stainless steel with an uncoated finish. The shoulder measures 0.5 inches in diameter and 0.375 inches in length, providing a precise bearing surface for rotating or sliding components. The 0.75-inch diameter head sits 0.3125 inches tall and accepts a 1/4-inch hex socket drive. The threaded shank is 3/8-16 UNC. This fastener is installed by machinists, millwrights, and maintenance technicians wherever a controlled-diameter pivot or locating pin is required.

Shoulder screws of this type are used in jigs, fixtures, die sets, linkage assemblies, and mechanical subassemblies where a precision unthreaded shoulder must carry a load, guide motion, or retain a bushing or bearing. The 18-8 stainless steel construction makes this screw suitable for applications exposed to mild corrosive environments, including food-processing equipment, wash-down assemblies, and outdoor machinery. The 3/8-16 UNC thread engages standard tapped holes in aluminum, steel, and stainless steel components.

Key Features

• 0.5-inch shoulder diameter provides a precise bearing surface for bushings, bearings, and sliding components
• 0.375-inch shoulder length suits shallow fixture and linkage applications
• 3/8-16 UNC thread for engagement in standard tapped holes
• 18-8 stainless steel construction offers corrosion resistance in mild chemical and moisture environments
• Uncoated finish maintains dimensional consistency without plating buildup
• 1/4-inch hex socket drive for use with standard Allen wrenches and hex-bit drivers

Compatibility

Designed as a standard shoulder screw for use in any application requiring a 0.5-inch shoulder diameter, 0.375-inch shoulder length, and 3/8-16 UNC threaded engagement in steel, aluminum, or stainless steel components.

Installation Notes

Installation requires a 1/4-inch hex key or hex socket driver. Verify that the mating tapped hole is clean and free of debris before threading to prevent galling on the stainless steel threads. Apply appropriate anti-seize compound if the screw will be installed into a stainless steel tapped hole to reduce the risk of thread seizure.
