It features an M8 x 1.25 internal thread and an M12 x 1.75 external thread, and is manufactured from 303 stainless steel with a bright finish for corrosion resistance. The overall installed length is 12.5 mm, making it suitable for applications where compact thread engagement is required. With a tensile strength of 10,625 pounds, this insert delivers reliable holding power. It is installed using a standard tap and is appropriate for use wherever a metric coarse thread locking solution is needed in metal or composite assemblies.\u003c\/p\u003e\n\u003cp\u003eThe 453-8 is used in mechanical, industrial, and trade assembly applications where an M8 internal thread must be locked into a parent material tapped to M12 x 1.75 metric coarse. The self-lock wall design creates thread interference that resists loosening under vibration and cyclic loading. Typical installation scenarios include equipment housings, brackets, and structural assemblies where thread pull-out resistance and locking retention are required. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and general mechanical service will find this insert appropriate for field repairs and OEM-style replacements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-lock wall design resists loosening under vibration and cyclic loads\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction with bright finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eM8 x 1.25 internal thread with 6H class of fit for standard metric fastener engagement\u003c\/li\u003e\n  \u003cli\u003eM12 x 1.75 external thread with 6G class of fit for precise installation\u003c\/li\u003e\n  \u003cli\u003eTensile strength of 10,625 pounds for demanding structural applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard tap type  -  no specialty installation tooling required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread locking insert for parent materials tapped to M12 x 1.75 metric coarse, providing an M8 x 1.25 internal thread.

Power down or de-energize any equipment fully before performing thread repair or insert installation in electrical or mechanical assemblies. Ensure the tapped hole is clean and free of debris before driving the insert to full depth.
