Value Collection SS6X03005-050BX M3x0.5 Cup Point Set Screw 50pk

Product Description

The VALUE COLLECTION SS6X03005-050BX is a metric cup point set screw designed for precision clamping and positioning applications across mechanical assemblies. Manufactured from 18-8 austenitic stainless steel to Grade A2, this fastener resists corrosion in wet, chemical, and outdoor service environments. The M3 x 0.50 thread with a 5 mm overall length makes it well suited for securing small shafts, collars, and components where a low-profile, headless fastener is required. Driven with a 1.50 mm hex key, it conforms to DIN 916 standards. This listing covers a minimum order quantity of 50 pieces, packaged as a single unit, making it appropriate for shop stock and service kits.

This set screw fits applications in HVAC equipment assembly, electrical enclosure hardware, pump and motor shaft collars, and general industrial maintenance. Trades including HVAC technicians, electricians, and plumbers encounter cup point set screws when servicing blower wheel hubs, motor couplings, valve stems, and panel hardware. The cup point geometry bites lightly into a shaft to resist rotation without requiring a flat, making it a common choice for cylindrical shafts in light-to-medium duty assemblies.

Key Features

• M3 x 0.50 metric thread, 5 mm overall length for compact, headless installations
• Cup point geometry provides positive grip on cylindrical shafts without requiring a machined flat
• 18-8 austenitic stainless steel, Grade A2 construction for corrosion resistance in wet and chemically exposed environments
• Conforms to DIN 916 fastener standard for consistent dimensional compliance
• 1.50 mm hex key drive allows installation in tight clearance areas
• Sold in a 50-piece minimum order quantity, suitable for stocking service vehicles and shop bins

Compatibility

Designed as a general-purpose metric set screw for use in mechanical assemblies requiring an M3 x 0.50 DIN 916 cup point fastener. Consult equipment documentation to confirm thread size and length requirements before installation.

Installation Notes

Installation requires a 1.50 mm hex key; use a calibrated torque driver where the equipment manufacturer specifies a tightening torque for M3 fasteners. De-energize and lock out any equipment before accessing shaft collars or rotating assemblies. Do not over-torque stainless steel fasteners, as galling can occur; applying an anti-seize compound rated for stainless steel is standard practice. Inspect the mating shaft surface for burrs or damage before seating the cup point to ensure proper holding force.
