b&m-TRIMSCREW
A metric screw with the additional ability to remove coating residues inside internal threads.
Developed to remove coating residues in nut threads, the b&m-TRIMSCREW® is an excellent alternative to screws with a scrape point. The b&m-TRIMSCREW® features three recesses that remove paint residues, weld spatter and blasting residue in the thread, and also remove partial deformations of the thread – preventing problems during the fastening process.
Functional principle
The three recesses in the span of the first four threads of the b&m-TRIMSCREW® remove coating residues in nut threads. This ensures that the thread is made workable again. The screw is used as both a tool and a fastener.
Benefits
- Problems when screwing into clogged nut threads are
eliminated, so that recutting threads is no longer required - The integrated dog point geometry improves the assembly
performance - Perfectly suited for components with internal threads
that have been powder-coated, painted or cathodic
dip-paint-coated (CDP) – time-consuming and cost-intensive
masking and unmasking of the threads is no
longer necessary - The screw has a metric ISO coarse thread in accordance
with DIN 13 – fine and inch threads are also possible
