M6 Phillips Drive Pan Head Thread Forming Screws Harden Steel Zinc Plated Fastener
M6 Phillips Drive Pan Head Thread Forming Screws Harden Steel Zinc Plated Fastener
Thread rolling screw is also named as thread forming screw or taptie screw , it has a triangle shape thread that from point to 1/3 of the threaded length . this triangle design can stop screw to back out and secure material more tightly .
● High tensile strength
● Perfect vibration resistance
● Good resistance loose
● Torsional strength
● Hard Material
● Wear resistance
Drill a Pilot hole before installing thread rolling screw , the hole will be screwed threads during thread rolling screw driving as self-tapping .
