Value Collection SS6X08020-100BX M8 Set Screw Cup Point

Product Description

The VALUE COLLECTION SS6X08020-100BX is a metric set screw with a cup point tip and hex socket drive, manufactured from 18-8 austenitic stainless steel (Grade A2). It measures M8 x 1.25 thread pitch with a 20 mm overall length and requires a 4 mm hex key for installation. Built to DIN 916 standards, this fastener delivers corrosion resistance suitable for both indoor and outdoor mechanical assemblies. It is a common choice for machinists, millwrights, and maintenance technicians who need a reliable grub screw in stainless steel construction.

This set screw is used in mechanical and industrial applications where a flush or below-surface fastening is required. The cup point digs into the mating surface to resist rotation and axial movement, making it appropriate for securing collars, hubs, pulleys, and similar components to shafts. It is suited for light to medium clamping force applications in assemblies where stainless steel corrosion resistance is a priority, including food-adjacent, marine, or humid environments.

Key Features

• Cup point tip bites into shaft or mating surface for positive axial and rotational hold
• 18-8 austenitic stainless steel (Grade A2) provides corrosion resistance without plating
• Conforms to DIN 916 standard for consistent thread form and dimensional accuracy
• M8 x 1.25 metric thread with 20 mm overall length
• 4 mm hex key drive for compact installation in tight clearance locations

Compatibility

Designed as a DIN 916 metric set screw for use in standard M8 x 1.25 threaded bores in mechanical assemblies requiring a cup point grub screw.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 4 mm hex key or Allen driver. Ensure the threaded bore is clean and free of debris before threading the screw in by hand to avoid cross-threading. Apply appropriate thread-locking compound if vibration resistance is required. Do not overtighten, as stainless steel fasteners are susceptible to galling without proper lubrication or anti-seize compound on the threads.
