It features a 1\/4-20 UNC thread, a shouldered body, and a dog-point tip for accurate engagement and positive alignment in mating holes. The lobed aluminum head allows hand tightening without tools. At 2-1\/4 inches in overall length with a 1\/8-inch dog-point tip, this screw is suited for applications where repeatable, tool-free clamping or positioning is required. It is commonly installed by machinists, mechanical assemblers, and maintenance technicians in jigs, fixtures, and machine sub-assemblies.\u003c\/p\u003e\u003cp\u003eThis thumb screw is used in industrial and manufacturing environments where hand-adjustable fasteners are needed for quick setup changes, workholding fixtures, or panel retention. The dog-point tip aids in locating the screw against a flat or into a detent, reducing movement under light loads. The black oxide finish provides mild corrosion resistance in dry indoor conditions. It is sold individually and fits standard 1\/4-20 UNC threaded inserts and tapped holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard tapped holes and inserts\u003c\/li\u003e\n\u003cli\u003e12L14 steel construction for precise machining tolerance and consistent thread quality\u003c\/li\u003e\n\u003cli\u003eLobed aluminum head enables hand tightening and loosening without tools\u003c\/li\u003e\n\u003cli\u003eDog-point tip, 1\/8 inch long and 5\/32 inch in diameter, for positive location and alignment\u003c\/li\u003e\n\u003cli\u003eShouldered body for controlled seating depth\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance in dry service environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4-20 UNC tapped holes in jigs, fixtures, machine panels, and similar assemblies where tool-free hand adjustment is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand or with a light assist from a flat-blade screwdriver on the lobed head.
