Value Collection SET-2-BT-SS Set Screw Assortment 210pc

Product Description

The VALUE COLLECTION SET-2-BT-SS is a 210-piece stainless steel set screw assortment covering thread sizes from 4-40 up to 5/16-18. All fasteners are Grade 303 stainless steel with a hex socket drive, making them suitable for applications where corrosion resistance and secure, tool-tightened clamping are required. Lengths range from 1/8 inch to 1/2 inch across the included size range. The kit ships in a compartmented plastic storage case that keeps each size separated and easy to inventory. Maintenance technicians, machine builders, and general fabricators reach for this type of assortment when working on equipment that requires frequent set screw replacement or adjustment across multiple shaft and collar sizes.

This assortment is suited for light industrial, commercial, and maintenance-of-equipment applications where stainless hardware is specified to resist rust or chemical exposure. The 12 distinct size-and-length combinations cover the most common inch-series set screw calls found on pulleys, shaft collars, shaft couplings, and similar mechanical components. The compartmented case keeps the assortment organized on a service truck, in a shop toolbox, or at a maintenance bench. Installers and technicians who regularly service pumps, fans, conveyor drives, or other rotating equipment will find the size range practical for day-to-day use.

Always de-energize and lock out rotating machinery before removing or installing set screws on shafts or collars. Do not over-torque small-diameter set screws; follow the equipment manufacturer's fastener torque guidance.
