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
    (UNC / UNF)
