Silverline Thread Repair Kit Helicoil Type M8 x 1.25mm (347853)

Product Information

Recoil inserts are generally made of type Stainless Steel 304 (AS 7245) Austenitic corrosion resistant steel rolled into a diamond shape cross-section.

Thread repair kit includes inserts for repairing tapped holes which have been stripped or damaged due to wear, corrosion and over-torque. During installation the inserting tool applies torque to the tang reducing the diameter of the leading coil permitting it to enter the tapped thread. The kit contains inserts, the proper size drill, high speed steel Heli-Coil tap and an installation tool.Silverline tools supplies a wide range of award-winning and top-rated hand and power tools across 26 categories. Place the insert onto the installation Tool and position the adjustable ring so that the insert tang is centred into the tang slot. The flexibility of our inserts enhances load bearing capacity by deflecting the residual forces into a helical direction, which is dispersed into the wall of the tapped hole.

This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees. This wire is then wound into a spiral coil which when installed into Heli-Coil tapped holes, provides permanent conventional 60° internal screw threads. Once fitted, the action of the radial pressure between the insertï¾’s coils and flanks of the tapped hole holds them in place securely.
