Your cart is empty. Description:Steel thread inserts can effectively improve screw connection, greatly improving the reliability. Used in all kinds of low strength materials, thread inserts can largely improve the wear resistance performance of screw connection, and avoid thread damage.
Features:Used for parts that requires frequent removing, it can greatly improve service life and wear-resistance of screw thread.Because of a certain elasticity, thread insert can even the load distribution on each thread, eliminate pitch and tooth deviation between screw and screw hole, and absorb vibration, thus increasing the screw thread connection strength and fatigue resistance.It can prevent screw from getting loose,especially used for products requiring high coefficient of insurance.Easy to maintenance, install a thread insert into a damage screw hole, then the screw hole can be used as normal, in order to avoid workpiece loss.

This is a great kit for repairing or creating threaded holes as long as it is done correctly. I've used this to repair damaged threads on my 3D printer and also used it for tapping new threads into aluminum to mount a DIN rail. The drill bit isn't the highest quality so I would be hesitant to use it for drilling into anything other than soft metals. The tap and helicoils work just fine though.

First off, you get what you pay for. This is an all-inclusive kit for a low price and in that alone it is decent value for money. Everything was there and for me it arrived in good condition, but that is more of a compliment to Amazon and the delivery driver than a reflection of care taken by the seller.Everything arrived just kind of thrown together in a bag with the helicoils in a baggy of their own inside the main bag. This isn't great to see and usually some effort would be made to keep a tap, drill and tools from rattling around during transit.The quality of the tools themselves is on the level of what you would expect at a discount hardware store or perhaps a more hardware-inclined dollar store. As far as I can tell the helicoils, the tap and drill and the insertion tools should all be the full cost of the kit, so you are getting roughly 3X the bang for your buck, but don't expect miracles when it comes to quality.With some more careful packaging I would give this four stars since it is as described and a great price, but someone else is going to be less lucky than me when they receive this as the packaging is abysmal. I would not use this on any critical machinery, but as far as I can tell the helicoils themselves are fine.
