Machined from steel with a black oxide finish, this fastener features a 5\/16-18 UNC thread and a swivel pad tip made from plastic, allowing the tip to pivot up to 7.5 degrees to conform to angled or irregular mating surfaces. The head measures 1.125 inches in diameter and 0.4375 inches in height, providing a secure grip for hand tightening without tools. Overall length is 2.4375 inches. It is manufactured under ISO 9001 quality standards.\u003c\/p\u003e\u003cp\u003eThis thumb screw is suited for use in fixtures, jigs, machine guards, and equipment panels where frequent hand adjustment is required. The swivel pad tip protects workpiece surfaces from marring during clamping. The black oxide finish provides mild corrosion resistance in indoor industrial environments. Typical applications include tool and die setups, instrumentation panels, and light-duty clamping fixtures where repeated access and adjustment are routine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKnurled head profile for secure hand grip without requiring tools\u003c\/li\u003e\n\u003cli\u003eSwivel pad plastic tip pivots up to 7.5 degrees to seat on angled surfaces\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish on steel construction for mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread standard for broad fitment in inch-system assemblies\u003c\/li\u003e\n\u003cli\u003eManufactured to ISO 9001 quality standards\u003c\/li\u003e\n\u003cli\u003eNo shoulder design for direct thread engagement into mating components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in inch-system mechanical assemblies requiring a 5\/16-18 UNC threaded thumb screw with a knurled head and swivel pad tip.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand or with light mechanical assistance into a pre-tapped 5\/16-18 UNC threaded hole.
