Value Collection SS6X05020-050BX M5 Set Screw Din 916

Product Description

The VALUE COLLECTION SS6X05020-050BX is a metric cup point set screw designed for mechanical assemblies requiring a secure, non-projecting fastener. It features an M5 x 0.80 thread profile with an overall length of 20 mm and is manufactured from 18-8 austenitic stainless steel, Grade A2, providing reliable corrosion resistance in moderate-exposure environments. The hex drive socket accepts a 2.50 mm hex key for installation. This fastener meets DIN 916 standards and is well-suited for use by machinists, millwrights, and mechanical contractors working with metric hardware in industrial or commercial equipment.

Cup point set screws like the SS6X05020-050BX are commonly used to lock collars, hubs, pulleys, and similar components onto shafts. The cup point geometry bites into the shaft surface to resist rotation and axial movement without requiring a projecting head. This makes it appropriate for applications where clearance around rotating assemblies is limited. Stainless steel construction suits environments where mild moisture or chemical exposure is a concern, such as food processing equipment, marine hardware, or outdoor machinery enclosures.

Key Features

• M5 x 0.80 metric thread with 20 mm overall length per DIN 916 standard
• Cup point geometry bites into shaft surface for positive locking without protrusion
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in moderate-exposure environments
• 2.50 mm hex drive socket for standard hex key installation
• Headless design maintains clearance around rotating or close-tolerance assemblies

Compatibility

Designed as a DIN 916 metric cup point set screw for use in standard M5 x 0.80 threaded applications including shaft collars, shaft couplings, pulleys, and similar mechanical components requiring a headless locking fastener.

Installation Notes

Installation is performed using a 2.50 mm hex key; ensure the key is fully seated in the socket before applying torque to avoid rounding the drive. Power down and de-energize any rotating equipment before accessing the fastener location. Clean the shaft surface of oil or debris before seating the cup point to ensure proper bite and holding force. Follow applicable machinery safety standards and equipment manufacturer guidelines during assembly or service.
