Inserts - Self Tapping, Slotted, Small Outside Diameter, Type 302

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.
