Value Collection SS6X04020-050BX Set Screw M4x0.70x20mm

Product Description

The VALUE COLLECTION SS6X04020-050BX is a metric cup point set screw manufactured to DIN 916 standards in Grade 18-8 austenitic stainless steel (Grade A2). It features an M4 x 0.70 thread pitch with an overall length of 20 mm and a 2 mm hex key drive. The cup point tip bites into the mating surface to resist rotation and axial movement without requiring a through-hole. Grade 18-8 A2 stainless provides corrosion resistance suitable for wet, chemical, or outdoor environments. Licensed tradespeople and maintenance technicians install these fasteners across mechanical assemblies, shaft collars, and positioning fixtures where a standard carbon steel fastener would corrode or contaminate.

This set screw is appropriate for light-to-medium duty clamping applications on shafts, hubs, pulleys, and collars in residential and commercial mechanical systems. The DIN 916 standard ensures dimensional consistency across metric assemblies. The cup point geometry concentrates clamping force at the contact circle, making it well suited for softer shaft materials where a cone or flat point would be used on hardened surfaces. Trade installers working in HVAC blower assemblies, plumbing valve stems, or poolside equipment enclosures commonly reach for this fastener when stainless is specified.

Key Features

• DIN 916 standard ensures metric dimensional compliance for consistent fit
• Cup point tip provides secure gripping on shaft surfaces without through-hole requirement
• Grade 18-8 austenitic stainless steel (A2) resists corrosion in wet and chemical environments
• 2 mm hex key drive for access in tight or recessed installation locations
• M4 x 0.70 thread pitch with 20 mm overall length suits a wide range of light-duty shaft collar applications

Compatibility

Designed as an OEM-style metric replacement set screw for mechanical assemblies requiring DIN 916 cup point fasteners in M4 x 0.70 thread size.

Installation Notes

Installation is performed with a 2 mm hex key; confirm the key is fully seated before applying torque to avoid rounding the socket. Degrease the shaft and thread bore before installation to ensure proper seating and prevent galling, which is a known risk with stainless fasteners. Always verify the mating component material is compatible with a cup point engagement before final tightening. If installed in an energized assembly, de-energize and lock out the equipment per applicable NFPA 70E or facility LOTO procedures before service.
