FLAT HEAD SIX LOBE Anti Loosening Screw, Stainless Steel Anti Loose Fastener For Industrial Equipment Assembly
Product Overview
FLAT HEAD SIX LOBE Anti Loosening Screw is a professional anti-vibration locking fastener independently developed for heavy-duty industrial assembly scenarios, combining flat countersunk head, six lobe anti-theft drive and permanent anti-loose coating three core designs in one product.
Ordinary machine screws will gradually loosen under long-term mechanical vibration, resulting in equipment abnormal noise, part falling off and safety hazards. Our FLAT HEAD SIX LOBE Anti Loosening Screw adds special nylon locking layer on thread, which can keep constant friction between threads after tightening, completely avoid loosening caused by high-frequency vibration.
Flat head design can sink into mounting hole to form smooth surface without protruding, six lobe inner recess prevents random disassembly by common screwdrivers, widely recognized by equipment manufacturers in new energy, automation, fitness equipment, intelligent monitoring industries.
