🔩 E-Z LOK 319-5 External Threaded Insert, C12L14 Carbon Steel, Meets AISI 12L14, 5/16"-18 Internal Threads, 7/16"-14 External Threads, Length 0.437", Made in USA (Pack of 10) Review

Excellent for repairing threads in soft materials such as aluminium. Fair price, fast delivery. Can save a damaged product.

Carburetor Bolt Crash Fixed (don't ask). I reamed out the damaged hole with a 3/8 bit, then used a 7/16-14 tap and it threaded well. Was able to save my new take and avoid a big problem!

Unlike other more expensive inserts like Time-sert, they do not require special tools, greatly increasing the price of repair inserts. I've been using them for many years. I don't trust the red locking compound on the threads. I take it off and use my own red LocTite. You can get them with thin walls or regular ones.

This little device saved me. I tore off the spigot from the cylinder head bolt. After drilling it out it turned out to be too big for a standard screw. You simply drill the right size hole for the insert, cut the hole and screw in the insert. You can use a flathead screwdriver, although I chose to purchase a dedicated insertion tool. The head is tight with no slip and my tractor runs great. The red thing in the thread is the thread blocker. It holds the insert firmly in place.
