Insert（Screw Type：Metric (Coarse) Thread Page3）

These products are used for reinforcing female threads. These can be used with damaged female threads or soft materials to enable screws/bolts to be tightened.
In general, coil inserts that have been machined into a coil shape are very common, but we also have a wide lineup that includes "self-tapping inserts", "inserts for resin", "insert nuts", "locking inserts", etc., enabling use to suit various environments or materials.
MISUMI enables spec searches and ordering quantities from just 1 piece. Tools are also sold in addition to the inserts themselves.

Iron, stainless steel, brass, phosphor bronze, Inconel, nitronics
[Size]
M1.4 to M39 are available as well as imperial sizes

Ensat Chip Free Long Type, Model 338

KKV

Ensat is an insert nut with high workability usable with resin, aluminum, etc., which easily cause female screw destruction with direct tap. It cuts material with the blade on its body, so no front tap is needed. Female screw reinforcement by Ensat enables aluminum and resin to be used for parts, which contributes to weight reduction. Ensat supports the force applied to the inner screw with a slightly larger outer screw, so it can endure a stronger force than a direct tap.
