It accepts a 7\/16-14 UNC internal thread and installs into a 5\/8-11 UNC tapped hole, with an overall length of 0.656 inches (21\/32 inches). The self-lock wall design resists loosening under vibration and dynamic loads without adhesives or locking compounds. With a rated tensile strength of 17,216 pounds, this insert is built for demanding fastening applications where thread integrity and corrosion resistance are critical. Licensed machinists, millwrights, and maintenance technicians typically install this type of hardware in metal assemblies requiring a reinforced or converted thread form.\u003c\/p\u003e\u003cp\u003eThe 303-7 insert is suited for use in light to heavy industrial assemblies, machinery repair, and OEM manufacturing where a permanent, self-locking thread is needed. The 5\/8-11 external thread requires a standard tap, keeping installation tooling straightforward. Its bright finish and stainless steel construction make it a practical choice in corrosive or washdown environments. This insert is sold individually with a minimum order quantity of 5 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-lock wall design resists thread loosening under vibration without added locking compounds\u003c\/li\u003e\n\u003cli\u003eGrade 303 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e7\/16-14 UNC internal thread, Class 2B fit\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC external thread, Class 2A fit, installed with a standard tap\u003c\/li\u003e\n\u003cli\u003eRated tensile strength of 17,216 pounds\u003c\/li\u003e\n\u003cli\u003eBright finish; overall length of 0.656 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any application requiring a 5\/8-11 UNC tapped host hole and a 7\/16-14 UNC internal thread form, following standard UNC thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 5\/8-11 UNC hole in the host material using a standard tap.
