Value Collection 93935 Set Screw 1/4-20 X 1/4 in Cup Point Ss 50pk

Product Description

The VALUE COLLECTION 93935 is a 1/4-20 UNC cup point set screw machined from grade 18-8 stainless steel. At 1/4 inch in length, this fully threaded fastener seats flush or below the surface of a workpiece and uses its hardened cup point to bite into a shaft or mating surface to resist rotation and axial movement. Drive is via a 1/8 inch hex key. Grade 18-8 stainless offers solid corrosion resistance for applications exposed to moisture, mild chemicals, or outdoor environments. These screws are packaged in quantities of 50, making them practical for bench stock or job-lot use by machinists, millwrights, pipefitters, and maintenance technicians.

Cup point set screws in 1/4-20 are commonly used to lock collars, hubs, pulleys, sprockets, and knobs onto shafts in light to medium-duty mechanical assemblies. The stainless construction makes them a common choice in food-service equipment, HVAC mechanical components, pump assemblies, and similar environments where carbon steel fasteners would corrode. The 50-piece pack suits repetitive production work or restocking a service van with commonly called-for hardware sizes.

Key Features

• Cup point geometry bites into shaft material to resist rotation and axial displacement without a through-hole
• Grade 18-8 stainless steel construction provides corrosion resistance in wet and mildly chemical environments
• 1/4-20 UNC thread is one of the most common inch-series thread standards for domestic mechanical assemblies
• 1/8 inch hex key drive allows installation in confined spaces with standard Allen wrenches
• 50-piece packaging supports bench stock, kitting, and multi-unit service work

Compatibility

Designed as a standard 1/4-20 UNC cup point set screw suitable for any application requiring this thread size, point type, and stainless steel material grade.

Installation Notes

Set screws are typically installed by machinists, millwrights, or maintenance technicians using a 1/8 inch hex key or Allen wrench. Ensure the mating shaft is clean and free of burrs before seating the cup point. De-energize or lock out any rotating equipment before adjusting or replacing set screws in live assemblies. Avoid over-driving, which can strip the hex socket or damage the shaft surface beyond the intended bite depth.
