FAQ

Q: Why is the washer important?

A: The washer acts as a seal. When tightened against the surface, it compresses to block water from entering the hole. This is critical for preventing leaks in roofing sheets or wall cladding.

Q: Should I choose Zinc Yellow or Ruspert?

A: Both are high quality. Use Zinc Yellow for general construction or interior/semi-outdoor use. Choose Ruspert if you are building near the coast, in a high-humidity area, or in an industrial environment where salt or chemicals may accelerate rusting.

Q: Do these self-tapping screws require pre-drilling?

A: Generally, yes. As ''Self-Tapping'' screws, they work best when a pilot hole is created first. This ensures the screw cuts a clean, tight thread, maximizing the pull-out strength of the fastener.

Q: Can I use these for timber?

A: Yes. Because they are self-tapping with deep threads, they offer exceptional holding power in dense timber, especially when fastening metal brackets or sheets to a wooden frame.
