Kennedy Thread Repair

Kennedy Professional Thread Repair Wire Inserts are the easiest and quickest inserts to install to repair damaged or worn threads, you simply screw the insert into the pre-drilled and tapped hole, until the drive tang breaks off. They can be used with plastics or other materials provided that the material is strong enough to withstand the expansion of the insert as the screw thread locks into the wall of the hole. They are also suitable for new applications where, because of their mechanical strength benefits their introduction may result in the use of thinner sections or lighter parent materials without sacrificing thread strength they can also be used for converting from metric to inch and vice versa.

Most inserts are 1.5x diameter for length. For example:- M6 is 9mm long.
Other lengths are available on request.

Available in Metric, UNC, UNF, BSF, BSP and BSW sizes.

For all dimensional specifications please refer to our catalogue.

Pozi Countersunk Woodscrew

A combination of 4CUT point, MULTIhead and patented ground serrations that makes a Spax screw one of the best woods screw on the market. The 4CUT point bores into wood and divides the fibres while the deep thread with ground serrations drive the screw on. This prevents the material from splitting. The patented MULTIhead has countersinking and stopping qualities at the same time. The ribs cut into the wooden surface, trimming off the drilled hole. The head can be driven home flush with the wood surface quickly and easily. The ribs also help prevent thread stripping when fixing hinges etc. Spax screws give trouble free fastening in all varieties of materials: hard or soft wood, plastics or thin sheet metal.
