 Böllhoff Helicoil Plus

HELICOIL® thread inserts create load-bearing joints in metal materials with low shear strength.
They are available in Free Running and Screwlock versions. The green or red colour simplifies identification even when installed.

Threads are reinforced whenever low-strength materials (e.g. aluminium, aluminium-magnesium alloys and fibre reinforced plastics) are used.
HELICOIL® thread inserts produce high-strength, wear- and heat-resistant threads of highest precision. The thread is wear resistant even in cases of frequent use.

The HELICOIL® is used in mechanical engineering and in the electronics, automotive and aerospace industries. HELICOIL® is also applied in gear housings, exhaust systems, engines and satellites, thread reinforcement, repeated installations, maintenance and repair as well as in lights, electrical appliances, hammer drills and printing presses.
HELICOIL® Plus thread inserts comply with a variety of requirements and industry standards, including those in the aerospace industry, and feature other approvals as well as suitability tests, e.g. in the field of power plant technology.
