Sized at 4-40 x 1\/4 inches overall length, this screw features an 82-degree flat head driven by a 1\/16-inch hex socket. It is fully threaded along its 1\/4-inch length, conforming to UNC thread standard and manufactured to ASME\/ANSI B18.3 and ASTM F835 specifications. The alloy steel construction with black oxide finish provides corrosion resistance suitable for indoor mechanical assemblies. Machinists, maintenance technicians, and precision equipment assemblers commonly work with this fastener size.\u003c\/p\u003e\u003cp\u003eThis screw is used in light mechanical assemblies where a low-profile, flush-mount fastener is required. The 4-40 thread size is common in instrument enclosures, electronics chassis, jigs, fixtures, and light-duty machine components. The black oxide finish reduces light reflection and offers moderate corrosion resistance in dry indoor environments. The fully threaded shank maximizes thread engagement in thin material applications. Sold individually with a minimum order quantity of 100 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head for flush or countersunk seating\u003c\/li\u003e\n\u003cli\u003e1\/16-inch hex socket drive for precise torque application in tight spaces\u003c\/li\u003e\n\u003cli\u003eFully threaded 1\/4-inch overall length for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction per ASTM F835 for reliable mechanical strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for reduced reflectivity and light corrosion protection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC replacement or specification fastener for applications requiring a 4-40 thread size flat socket cap screw per ASME\/ANSI B18.3 and ASTM F835.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/16-inch hex key or hex socket bit driver. Ensure the mating tapped hole is properly sized and deburred before threading to avoid cross-threading. Power down or de-energize any equipment before fastener replacement in electrical or electronic enclosures.
