Thread Reinforcement & Thread Repair BaerCoil® Wire Thread Inserts - Type: “free running“ BaerCoil® thread inserts are made from austenitic chromium-nickel steel (stainless steel AISI 304 with a material tensile strength of at least 1400 N/mm²). In production the wire is swaged in cold-form to a rhombic cross-section, which ensures performance and maximum space utilization. With BaerCoil® thread inserts you achieve a better thread connection in regard to wear resistance, thread abrasion, surface finish, corrosion- and heat resistance than with any other single screw connection. BaerCoil®...

www.baercoil.com Protection against wear of a thread BaerCoil® thread inserts protect the thread against wear and damage in all metals and their alloys, as e.g. aluminum, magnesium, titanium, copper, steel, plastic and other materials. The thread insert is very hard and has a premium surface finish. Since the surface has minimal roughness, less friction force affects the thread when inserting the screw. The decrease in thread friction force also minimizes wear. Corrosion-resistance BaerCoil® thread inserts also have excellent corrosion-resistance properties. This ensures applicability in...

Design The outer diameter of non-installed BaerCoil® thread inserts is larger by a fixed measure than the receiving thread. This is necessary in order to apply radial pressure during installation to the inner thread of the receiving thread. This radial pressure safely and firmly seats the thread insert in the receiving thread. Additional securing elements are, therefore, not required. The thread insert adjusts to the thread turns and slightly expands in length. This is why the length of the thread insert can only be measured when installed since it lengthens while being pressed together as...

For design of screwed connections under thermal stress, the changes of temperature-department material parameters must be taken into account. Intermediate lengths are available, too. For these guide values, the screw is the weaker joint member. Lengths can be shorter than recommended nominal lengths if tests confirm this.

Installation by hand 1. Drilling 3. Installing thread inserts Clear the damaged thread with a standard drill. To repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap with pilot nose. Optionally you can countersink the borehole. Use the special BaerCoil® tap for cutting the holding thread into the cleared hole. BaerCoil® taps are suitable for blind- and through holes. It‘s recommended to use a suitable cutting oil. Place insert on installing tool and position the adjustable ring that the insert tang is centred in the tang slot. Wind insert in with light...
