PennEngineering's MAThread anti cross-threading screw technology corrects off-angle installations, reliably aligning components and easily sliding through potentially clogged internal threads.
PennEngineering has released a captive screw assembly for permanent installation into almost any panel hardness or material.
Its MAThread anti cross-threading screw technology corrects off-angle installations, reliably aligning components and easily sliding through potentially clogged internal threads.
These flare-in panel fasteners (Type PF11MF with knurled cap and Type PF12MF with smooth cap) enable subsequent access to an assembly.
The Type PF11MF meets UL 508 operator access area requirements and The Type PF12MF meets UL 1950 service access area requirements.
Thread sizes range from #4-40 through 1Z4-20 and M3 through M6 and the anti cross-thread feature promotes quick installation.
As the threads come into contact, the anti cross-thread begins to cam over the female thread.
The two thread helixes align and the fasteners drive quickly and properly with reduced effort.
The panel fasteners install flush on the back side of a panel using minimal squeezing force with a punch and anvil to flare their retainer.
A shoulder on the retainer provides a positive stop to promote easier installation and improved performance.
They are ideally suited for close centreline-to-edge applications and will not mar painted surfaces.
