Value Collection R57600648 Shoulder Screw 3/4 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600648 is a shoulder screw manufactured from 18-8 stainless steel with an uncoated finish. The shoulder measures 0.75 inches in diameter and 1.75 inches in length, providing a precise ground surface for use as a pivot, spacer, or bearing journal. The threaded portion is sized 5/8-11 UNC, and the fastener is driven by a 3/8-inch hex socket. The head measures 1 inch in diameter and 0.5 inches in height. This type of fastener is installed by machinists, maintenance technicians, and fabricators in applications requiring a controlled-diameter shank to locate or retain mating components.

Shoulder screws of this size range are commonly used in fixture assemblies, jigs, linkage mechanisms, and pivot-point applications in both industrial and light commercial settings. The 18-8 stainless steel construction offers resistance to oxidation and mild corrosion, making it suitable for environments where plain steel fasteners would degrade. The 5/8-11 UNC thread engages standard tapped holes in steel, aluminum, and other common base materials. Package quantity is 1 piece.

Key Features

• Shoulder diameter of 0.75 inches provides a precision bearing or pivot surface
• Shoulder length of 1.75 inches suits medium-depth pivot and spacer applications
• 18-8 stainless steel construction resists oxidation and mild corrosion
• 5/8-11 UNC thread engages standard tapped holes in common base materials
• 3/8-inch hex socket drive for use with standard hex keys or socket drivers
• Uncoated finish maintains dimensional accuracy at the shoulder surface

Compatibility

Designed as a standard shoulder screw for use in tapped 5/8-11 UNC holes in fixtures, jigs, linkages, and pivot assemblies requiring a 0.75-inch precision shoulder diameter.

Installation Notes

Installation is performed by hand-threading into a pre-tapped 5/8-11 UNC hole, then seating with a 3/8-inch hex key. Ensure the mating bore is sized to match the 0.75-inch shoulder diameter for proper fit. Clean the tapped hole of debris before installation. Do not overtighten, as the shoulder rather than the thread carries the primary load in most pivot and spacer applications.
