Value Collection SS6X08050-025BX Set Screw M8x1.25x50mm

Product Description

The VALUE COLLECTION SS6X08050-025BX is a metric hex-drive cup point set screw used to secure components against rotation or axial movement on shafts and in assemblies. Manufactured from Grade 18-8 austenitic stainless steel (Grade A2) and conforming to DIN 916, this fastener delivers corrosion resistance suitable for wet, chemical, or food-adjacent environments. The M8 x 1.25 thread pitch paired with a 50 mm overall length suits medium-duty clamping applications. A 4 mm hex key drive allows installation in confined spaces. Licensed trades, maintenance technicians, and fabricators working with stainless assemblies use this screw where a flush or sub-flush seating point is required.

This set screw is suited for general industrial, mechanical, and trade fabrication applications where a metric fastener with corrosion-resistant properties is needed. Typical uses include shaft collars, pulleys, gears, couplings, and structural fixtures. The cup point creates a small indent in the mating shaft surface, providing positive grip and resistance to vibration-induced loosening. Applications span HVAC equipment assemblies, plumbing component fabrication, electrical enclosure hardware, and pool or pump equipment where moisture exposure is common.

Key Features

• M8 x 1.25 metric thread, 50 mm overall length for medium-depth clamping
• Cup point geometry indents mating shaft surface for positive anti-rotation grip
• Grade 18-8 austenitic stainless steel (Grade A2) provides strong corrosion resistance
• Conforms to DIN 916 fastener standard for dimensional consistency
• 4 mm hex key drive for use with standard L-keys or T-handle drivers in tight clearances
• Headless design allows fully recessed installation flush with or below the workpiece surface

Compatibility

Designed as a DIN 916 metric set screw suitable for M8 x 1.25 threaded bores in shaft collars, couplings, pulleys, and similar mechanical components requiring a cup point fastener.

Installation Notes

Installation is performed with a 4 mm hex key; verify the key is fully seated before applying torque to avoid rounding the drive socket. Ensure the mating bore is clean and free of debris before threading in the screw. In stainless-to-stainless assemblies, apply an anti-seize compound to reduce the risk of galling. Always de-energize or lock out equipment before accessing rotating or pressurized assemblies during installation or removal.
