Value Collection SS6X03004-050BX M3 Set Screw Din 916

Product Description

The VALUE COLLECTION SS6X03004-050BX is a metric cup point set screw used to secure components such as collars, pulleys, and gears onto shafts without a protruding head. Manufactured from Grade 18-8 austenitic stainless steel (Grade A2), this fastener provides reliable corrosion resistance for both indoor and outdoor applications. The M3 x 0.50 thread pitch and 4 mm overall length make it suited for light assemblies requiring precise axial clamping. Drive engagement is via a 1.50 mm hex key. This screw conforms to DIN 916, ensuring dimensional consistency for metric applications. Machinists, maintenance technicians, and mechanical assembly professionals are the primary installers.

This set screw is appropriate for use in mechanical assemblies across industrial, commercial, and light manufacturing environments. The cup point geometry bites into the mating shaft surface to resist rotational slipping under moderate torque loads. Applications include shaft-to-hub connections in small motors, precision instruments, and conveyor components where a flush or recessed fastener is required. The stainless steel construction makes it suitable for wash-down environments or installations where mild corrosive exposure is a concern.

Key Features

• Cup point tip digs into shaft surface for firm rotational and axial hold
• Grade 18-8 austenitic stainless steel (Grade A2) resists corrosion in wet or mildly corrosive environments
• Conforms to DIN 916 for consistent metric dimensional standards
• M3 x 0.50 thread with 4 mm overall length fits tight-clearance assemblies
• 1.50 mm hex key drive allows installation in recessed or confined locations
• Headless design sits flush or below the mating surface to eliminate snag points

Compatibility

Designed for use in any metric M3 x 0.50 threaded bore requiring a DIN 916 compliant cup point set screw, including shaft collars, hubs, and mechanical clamping assemblies in standard metric hardware systems.

Installation Notes

Installation requires a 1.50 mm hex key or Allen driver; use a calibrated torque tool appropriate for M3 fasteners to avoid over-driving and stripping the hex socket. Ensure the mating shaft and threaded bore are clean and free of debris before installation. Stainless fasteners are susceptible to galling during installation — apply an anti-seize compound rated for stainless steel if the screw will be removed periodically. Follow applicable machinery safety standards and power down or de-energize equipment before servicing any shaft-mounted component.
