The VALUE COLLECTION MASC0050012CP is a fully threaded socket cap screw engineered for precision fastening in mechanical assemblies, equipment fabrication, and maintenance applications. The screw features an M5 x 0.8 thread profile with a 12 mm length under head, a socket cap head style, and a hex socket drive. Constructed from 18-8 austenitic stainless steel (Material Grade A2), it delivers reliable corrosion resistance in wet, chemical, or outdoor service environments. Compliance with DIN 912 ensures dimensional consistency for drop-in replacement or new assembly work. This fastener is installed by machinists, millwrights, HVAC technicians, plumbers, and maintenance professionals across a wide range of trade and industrial settings.
This socket cap screw is suited for general mechanical assemblies, equipment panels, brackets, and component mounting where a low-profile hex-drive fastener is required. The fully threaded body allows full thread engagement across the entire shank length, making it appropriate for shorter grip-length applications and tapped-hole installations. Minimum order quantity is 100 pieces, making this screw practical for shop stock, service van inventory, or production-run fastener needs.
Designed as an OEM-style or aftermarket replacement socket cap screw for any application requiring an M5 x 0.8, 12 mm fully threaded DIN 912 hex socket fastener in stainless steel.
Installation is performed with a properly sized hex key or hex driver bit matching the M5 socket cap head. Confirm thread engagement in the tapped hole is adequate before applying torque. Use appropriate torque guidelines for 18-8 stainless steel to avoid galling — applying anti-galling compound to the threads is a common practice with stainless fasteners. De-energize or shut down any equipment being serviced before accessing fastened components.
