Thread Forming Screws
Thread Forming Screws for Metal applications
These case hardened screws benefit from a tri-lobular thread design, which enables the screw to be assembled into untapped applications, creating a reusable thread whilst forming a strong connection with the parent material. The clear advantage is in the time saved in pre-tapping.
Thread Forming Screws for Plastic applications
With the huge increase in the use of plastic materials across the manufacturing spectrum, the demand for specialist thread forming fasteners has led to a series of design innovations.
The original design utilised a combination of self tapping 45 degree thread with a tri-lobular thread shape.
In an effort to reduce material displacement and avoid fracturing, Hi-low dual threads aimed to improve assembly performance and pull out strength.
The latest high tech thread returns to a traditional round thread but with an extra sharp deep thread and reduced core. The resulting 30 degree thread angle aims to cut in to the hardest materials with minimum displacement and maximum pull out strength.
