TRUSCO Insert Screw Enzat 309 Type Extra Coarse External Thread M4XP0.7-2.5DNS 309-M4XP0.7-2.5DNS 1 PK

Catalog number: 309-M4XP0.7-2.5DNS Features: ● Enzat [R] is an easy-to-use insert nut that can be used on resin and wood, where female threads are easily broken with a straight tap. ● It has a cutting edge with a split groove shape and cuts the mating material with its own blade, so no pre-tap is required. ● 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 a straight tap. ● Reinforcement using Enzat [R] is limited by the inherent shear strength of the mating material or the mechanical strength of the bolt used. ● Type 309 (split groove type) is suitable for resin and wood, where female threads are easily broken. Applications: ● For reinforcing and preventing damage to internal threads and strengthening the fastening of external threads.
