Use:
Reamer screws are suitable for applications where wood is fixed to mild steel or aluminum, and there is no need for pre-drilled holes in most applications.

Prompt:
The length of the screws does not represent the usable length of the thread/thickness of the wood, maximum wood depth ~7/8" - Maximum metal thickness screws can be drilled ~1/8" - With the T-25 Torx/Star drill bit, the drilling point must be stiffer than the drilling material, install with a standard impact drive to install the screws at medium speed. Going too fast can damage the drill bit.

Dimensions: Head width .38", overall length 1-5/8", shank diameter .19".

Peculiarity:
The self-drilling wing passes through the wood and breaks as soon as it comes into contact with steel or aluminum, and then the threads will mesh, but are not suitable for welds or tempered metals
