TRUSCO Enzat [[R Down]] 307 Steel Three Hole Short Size M3 P0.5 L4 307-M3-P0.5-1.3DNS 1 PK

Catalog number: 307-M3-P0.5-1.3DNS Features: ● Enzat [R] is an insert nut with good workability that can be used for resin and aluminum where direct tapping is likely to cause female thread destruction. ● It has a cutting edge with a split groove or three holes, and cuts the mating material with its own blade, so no pre-tapping is required. ● By reinforcing the female thread with Enzat [R], it is possible to make parts from aluminum or resin, which helps to reduce weight. ● Enzat [R] supports the force applied to the internal thread with an external thread that is one size larger, so it can withstand higher forces than direct tapping. ● Reinforcement using Enzat [R] is limited by the inherent shear strength of the mating material or the mechanical strength of the bolt used. ● Type 307 (three-hole type) is suitable for mild steel, high-strength aluminum alloys, and hard resins that are prone to cracking. Applications: ● For reinforcing and preventing damage to internal threads and strengthening the fastening of male threads.
