Value Collection 93965 Set Screw 3/8-16 X 1-1/2 in Cup Point Ss

Product Description

The VALUE COLLECTION 93965 is a 3/8-16 UNC cup point set screw machined from grade 18-8 stainless steel. At 1-1/2 inches in overall length, it is driven with a 3/16-inch hex key and seats with a cup point that bites into the mating shaft surface to resist rotational movement. Grade 18-8 stainless provides solid corrosion resistance in wet, chemical, or outdoor environments where standard carbon steel fasteners would corrode. This screw is used by machinists, millwrights, pipefitters, and maintenance technicians whenever a flush or recessed fastening point is required and corrosion resistance is a priority. Sold in a package of 25.

Cup point set screws in this size range are common in shaft-collar and pulley assemblies, HVAC fan wheel hubs, pump impeller retention, and equipment mounting applications across light industrial and mechanical service work. The 3/8-16 UNC thread is a standard coarse-thread designation, making these compatible with tapped holes machined to common inch-standard tooling. The stainless construction makes them a preferred choice over zinc-plated or black-oxide alternatives in corrosive or sanitary environments.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard inch-tapped bores
• 1-1/2 inches overall length for deep engagement in thick collars and hubs
• Cup point geometry bites into shaft surface for strong rotational and axial hold
• Grade 18-8 stainless steel construction resists corrosion in wet and chemical environments
• 3/16-inch hex drive for standard Allen key installation
• Pack of 25 for shop stock or multi-point collar assemblies

Compatibility

Designed as a standard 3/8-16 UNC cup point set screw suitable for any tapped bore conforming to 3/8-16 UNC inch-standard thread specifications.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver. De-energize and lock out all rotating equipment before servicing shaft collars, pulleys, or hubs that use set screws. Ensure the mating bore is clean and threads are free of debris before seating the screw. Do not exceed the torque rating of the tapped hole material, and verify thread engagement depth is adequate before returning equipment to service.
