Gibraltar STR60112C16 Shoulder Screw 303 Ss 1/2x1 in 3/8-16

Product Description

The GIBRALTAR STR60112C16 is a hex socket shoulder screw machined from 303 stainless steel, designed for precision fastening applications where a hardened, accurately dimensioned shoulder is required as a pivot point, guide pin, or bearing journal. The shoulder diameter measures 0.5 inches and the shoulder length is 1 inch. The threaded portion is sized at 3/8-16 UNC. Drive is a 1/4 inch hex socket, making installation straightforward with a standard hex key or bit. At 0.04 pounds per package of two pieces, this screw is suited for light mechanical assemblies requiring corrosion resistance and dimensional consistency.

This shoulder screw is used in mechanical, industrial, and trade applications where a smooth, close-tolerance shank is needed to act as a shoulder, guide, or pivot within a mating component. Common installation scenarios include linkage assemblies, fixture jigs, cam followers, and precision machine components. The 303 stainless steel grade provides good machinability and corrosion resistance, making it appropriate for environments with moderate moisture or chemical exposure. Each package contains two screws.

Key Features

• Shoulder diameter of 0.5 inches provides a precision bearing or pivot surface
• 1 inch shoulder length accommodates standard mating component depths
• 3/8-16 UNC thread for secure engagement in standard tapped holes
• 1/4 inch hex socket drive compatible with common hex keys and insert bits
• 303 stainless steel construction resists corrosion in moderate-duty environments

Compatibility

Designed as a standard shoulder screw for use in mechanical assemblies, jigs, fixtures, and equipment requiring a 0.5 inch shoulder diameter and 3/8-16 UNC threaded section.

Installation Notes

Installation is performed by maintenance technicians or machinists using a 1/4 inch hex key or socket bit driver. Ensure the mating tapped hole is clean and threads are in good condition before installation. De-energize or lock out any equipment before servicing assemblies containing this fastener. Do not overtighten; apply only sufficient torque to seat the head flush against the mating surface without distorting the shoulder.
