{"product_id":"imperial-unf-hexagon-set-screws-bzp","title":"Imperial UNF Hexagon Set Screws BZP","description":"\u003cp\u003eWhen reliability, precise adjustment, and strong holding power are non-negotiable, these Imperial UNF Hexagon Set Screws BZP deliver consistent performance. Unlike standard bolts that feature a partial shank, these set screws are fully threaded from the tip right up to the underside of the hex head. This design maximises thread contact, making them the preferred fastener choice for securing components in tapped holes, machinery, and assemblies requiring uniform tension distribution along the entire length of the screw.\u003c\/p\u003e\n\u003cp\u003eThe Unified National Fine (UNF) thread pitch provides significant advantages over coarser thread alternatives. Because fine threads have a smaller helix angle and a larger minor diameter, they offer greater tensile strength and superior resistance to loosening caused by operational vibration. This makes UNF set screws particularly suitable for classic automotive repairs, precision machinery, engine components, and industrial equipment where exact torque management and strong holding force are paramount.\u003c\/p\u003e\n\u003cp\u003eProtected by a Bright Zinc Plated (BZP) coating, these steel set screws are built to withstand standard indoor environmental conditions. The zinc layer acts as a sacrificial barrier against moisture and oxidation, preventing premature rust and extending the working life of your fasteners. Beyond durability, the bright finish imparts a crisp, clean look to finished assemblies, making them ideal for visible restorations and professional fabrications.\u003c\/p\u003e\n\u003cp\u003eEngineered with a standard hexagonal head, these fasteners allow for easy installation using common socket sets, ring spanners, or open-ended wrenches. This ensures efficient torque transfer and simple maintenance access even in tight mechanical spaces. Whether you are conducting routine machinery maintenance, restoring vintage vehicles, or completing custom engineering projects, these imperial set screws offer the precise fit, strength, and corrosion protection your work demands.\u003c\/p\u003e","brand":"Electro South West Ltd","offers":[{"title":"1\/4\" x
