The VALUE COLLECTION SS6X08040-025BX is a metric cup point set screw used to secure components on shafts, collars, and assemblies without a protruding head. This fastener features an M8 x 1.25 thread and a 40 mm overall length. The cup point geometry bites into the mating surface to resist rotation and axial movement under load. Manufactured from 18-8 stainless steel in Austenitic Grade A2, it resists corrosion in wet, chemical, and outdoor environments. The hex socket drive accepts a 4 mm hex key for installation in tight clearance areas. Suitable for general industrial, mechanical, and trade assembly applications where a headless, flush-mount fastener is required.
This set screw is used wherever a threaded grub screw is needed to lock rotating or sliding components in position. Typical applications include motor shaft collars, pulley hubs, coupling assemblies, HVAC equipment brackets, and plumbing or mechanical subassembly fixtures. The stainless steel construction makes it appropriate for indoor and outdoor use, as well as light corrosive environments where carbon steel fasteners would degrade. Sold in a minimum order quantity of 25 pieces with a package quantity of 1, making it suited for small-batch maintenance kits and service stock.
Designed as a DIN 916 standard metric cup point set screw suitable for any M8 x 1.25 threaded hole requiring a headless grub screw in trade and industrial assembly applications.
Installation is performed by threading the screw into the tapped hole using a 4 mm hex key. Ensure the mating threads are clean and free of debris before installation. Apply appropriate thread-locking compound if vibration loosening is a concern in the application. Always verify thread engagement depth meets the requirements of the assembly before torquing.
