Value Collection R40343412 Set Screw 8-32 Cup Point Ss

Product Description

The VALUE COLLECTION R40343412 is a cup point set screw designed for secure, low-profile fastening applications in mechanical assemblies. Manufactured from Grade 18-8 stainless steel, this fastener resists corrosion and holds up in environments where moisture or mild chemicals are present. The 8-32 UNC thread profile and 3/16-inch overall length make it suited for compact clamping applications where a standard hex socket drive is preferred. A 5/64-inch hex key seats the screw and drives the cup point into the mating surface, creating a firm, bite-style hold. Maintenance technicians, millwrights, and trade professionals install these in shafts, collars, and assemblies requiring a flush or recessed fastener.

This set screw is used in light-duty to medium-duty mechanical assemblies across HVAC, electrical, plumbing, and general trade applications. Typical use cases include securing shaft collars, pulleys, knobs, and adjustment mechanisms where a protruding fastener head is not acceptable. The cup point digs into the mating shaft surface to resist rotational and axial movement. This item is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Cup point geometry bites into mating shaft surface to resist rotation and axial movement
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or mildly chemical environments
• 8-32 UNC thread standard ensures broad compatibility with standard tapped holes
• 5/64-inch hex drive allows installation with a standard Allen key in tight clearance spaces
• 3/16-inch overall length suits compact shaft collar and pulley assemblies
• Headless design sits flush or recessed, eliminating snag points in moving assemblies

Compatibility

Designed as a standard UNC set screw for use in any tapped 8-32 hole requiring a cup point, headless fastener in stainless steel.

Installation Notes

Installation is performed with a 5/64-inch hex key. De-energize and lock out any equipment before servicing rotating assemblies. Do not overtighten, as excessive torque may strip the 8-32 thread or damage the mating shaft. Follow applicable mechanical assembly standards and equipment manufacturer guidelines when installing fasteners in load-bearing or safety-critical applications.
