Self tapping slotted insert
Self tapping slotted insert
The self tapping slotted insert is a self cutting hardened steel threaded bushing that can cut its own thread in the receiving material because of the combination of the cutting slot with the special outer thread. This results in a wear-resitant internal thread that can be subjected to heavier loads and is still relatively short.
Drill, screw and done!
The self tapping slotted insert is available in brass, hardened steel, stainless steel303 and stainless steel 316
Description
The self tapping slotted insert can cut it's thread in the pre-drilled hole thanks to the combination of the selftapping cutting slot and the special (non-metric) outerthread.
Best mounted in a countersunk and pre-drilled hole in materials such as thermoplastics, cast iron, hard- and exotic wood.
This self tapping slotted insert is also the ideal solution for innerthread repair.
Why use a self cutting slotted insert?
The self tapping slotted insert can be mounted in a pre-drilled hole without pre-cutting or tapping the thread by the use of a manual tool for self-tapping inserts type 610 or the mechanical tool for self-tapping inserts type 620 that can be mounted on a cordless drilling machine, both hold the innerthread of the insert, so that the self cutting outerthread can be screwed into the hole. This way, the anchoring is very firm because of the larger outer diameter of the bushing resulting in higher pull-out values in the softer receiving material and very wear resistant because the bushing is made of hardened steel or stainless steel.
How do you install selftapping threaded inserts?
Here are the three key steps:
Begin by drilling a central hole using an appropriate drill bit and chamfer the hole sligthly and screw in the threaded selftapping insert with the slot facing the hole. This can be done without a tool for a test or very small quantities. You also have the option to purchase the corresponding installation tool for screw inserts type 620 that makes a correct installation of selftapping slotted inserts easier with the use of a cordless drill. Once completely screwed in the hole, you can unscrew the bolt or installation tool while unblocking the outerthread from the insert. Manually, this should be done with a wrinch or the outer unblocking pins of the tool 620 will do that automatically when reversing the screwing.Tip for swift mounting of selftapping inserts with cutting slot when using a tool 620.
Self tapping insert for aluminium?
You can use the self cutting slotted inserts in light alloy, but theory teaches us that "materials that are more difficult to machine" are better served with a self-tapping insert with 3 holes because then there is no deformation during mounting, much less tension is left around the insert and less force is needed to screw it in the pre-drilled hole therefor the tool remains more wear-resistant.
Available in steel zinc plated, brass, stainless steel 303 and 316 from M2 up to M24!
