Product Overview
Vinahardware’s 8105.0.12151 hex-flange bolt locks timber, sheet-metal or composite parts with one tool, no washers required. The built-in 18 ° flange spreads load, while optional radial serrations bite into lacquered steel or powder-coat finishes for anti-slip performance. A deep-black oxide layer delivers an industrial look and passes a 72-hour salt-spray test; alternative zinc or nickel platings are ready for coastal or food-grade projects.
