What this screw does Hex-socket machine screw (internal hex drive) designed for secure, flush fastening where a strong, corrosion-resistant fastener is required. Ideal for assembling metal, plastic, and composite parts where a clean, low-profile head and reliable thread engagement are needed. Key benefits Corrosion resistance: Made from stainless steel 304 (18-8), offering better rust resistance and longer life than plain steel or zinc-plated fasteners in most indoor and outdoor environments. Strength and reliability: 304 stainless provides good mechanical strength for general-purpose fastening applications. Easy installation: 5/32" (0.16") internal hex drive accepts standard Allen wrenches for controlled tightening and removal. Full-thread design: Full 1/4-20 UNC threads along the shaft ensure maximum grip and adjustable clamping length. Precise specifications (do not alter) Drive size: 5/32 inch (0.16 inch) internal hex Thread size/type: 1/4-20 UNC (20 TPI), full thread Thread (shaft) length: 5 cm (50 mm) Head diameter: 1.1 cm (11 mm) Head height: 0.3 cm (3 mm) Material: Stainless steel 304 (18-8) Compatibility and fit Fits standard 1/4-20 UNC tapped holes and nuts used in U.S. standard equipment. Use a 5/32" Allen (hex) key or bit for installation and removal. Full-thread shaft works where full engagement or fine adjustment is required along the entire length of the screw. Typical applications (practical examples) Equipment assembly: Securing panels, brackets, or components on industrial machines and fixtures where a durable, corrosion-resistant fastener is required. Electronics and enclosures: Fastening chassis, access covers, and internal mounts where a low-profile head and precise thread engagement are important. Furniture and outdoor fixtures: Connecting metal frames or hardware for outdoor furniture, signage, and installations exposed to weather (304 stainless offers good resistance in these conditions). Performance and handling tips Use the correct 5/32" hex key to avoid stripping the internal socket. 304 stainless is corrosion-resistant for most applications but is not a marine-grade alloy; avoid prolonged direct exposure to highly corrosive saltwater if maximum corrosion resistance is required. Inspect thread fit and clearances before final tightening to ensure full engagement and proper clamping force. This screw provides a dependable, corrosion-resistant fastening solution where 1/4-20 UNC full-thread length and a 5/32" internal hex drive are required.
