E-z Lok 653-10 Thread Locking Insert M10 X 1.5 Stainless

Product Description

The E-Z LOK 653-10 is a standard wall thread locking insert machined from 303 stainless steel. It accepts an M10 x 1.50 internal thread and installs into a 9/16-12 externally threaded host material, providing a durable, corrosion-resistant thread form in softer base materials or damaged thread bores. The insert measures 0.515 inches in length (33/64 inches) and is rated for both Metric Coarse and Metric Fine thread standards. Internal thread class of fit is 2B; external thread class of fit is 2A. Bright finish. Designed for installation with a standard tap. Maintenance technicians, machinists, and field service professionals install this type of insert to restore or reinforce threaded connections.

This insert suits residential and commercial applications where a metric internal thread must be established or repaired in a tapped 9/16-12 bore. Common install scenarios include equipment housings, machinery frames, and structural assemblies where thread integrity and corrosion resistance are required. The 303 stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact. Minimum order quantity is 5 units; package quantity is 1.

Installation Notes

Installation is typically performed by machinists, maintenance mechanics, or field service technicians. Prepare the host bore with a standard 9/16-12 tap before driving the insert. Follow torque and thread engagement guidelines from the host material manufacturer; do not exceed the material yield when seating the insert. Confirm thread class compatibility with mating fasteners before final assembly.
