Set screws are headless fasteners that thread fully into a tapped hole to secure a component — such as a collar, gear, or pulley — against a shaft without protruding hardware. The nylon soft tip protects the mating shaft surface from marring while still providing reliable holding force. The hex socket drive accepts a standard hex key for installation and removal. Grade 8 alloy steel construction provides high tensile strength suited for demanding mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for mechanical and industrial applications where shaft-to-hub locking is required without surface damage to the shaft. Common install scenarios include HVAC blower wheel hubs, motor shaft collars, pump impeller assemblies, and general mechanical equipment. The 1\/4-20 UNC\/UNF thread standard ensures broad compatibility with standard tapped holes found in light to medium-duty assemblies. Thread length measurement covers the full 1\/2 inch body length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSoft nylon tip protects shaft surfaces from scoring or marring during and after installation\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for use with standard hex key or Allen wrench\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC\/UNF thread standard fits widely available tapped holes\u003c\/li\u003e\n  \u003cli\u003eFull-body thread length of 1\/2 inch for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below surface for clean, low-profile installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 x 1\/2 inch soft-tip set screw for use in any tapped hole meeting the 1\/4-20 UNC or UNF thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the set screw into a pre-tapped 1\/4-20 hole using a properly sized hex key. Ensure the mating component is correctly positioned on the shaft before fully seating the screw.
