Frequently Asked Questions

What does "YHB" mean?

YHB stands for "Star Countersunk Head". The screw head has a star (Phillips) drive profile and a countersunk form, allowing it to be flush with the mounting surface. It provides an aesthetic and secure connection.

Which tip should be used?

For 4.8 mm diameter drill bit screws, a PH2 star tip is usually recommended. The correct tip selection prevents damage to the screw head and optimizes torque transfer.

What materials can it be used with?

It can be used with thin-to-medium thickness metal sheets/profiles (up to 3-4 mm), wood, MDF, and plywood. Pre-drilling is recommended for very thick metals or hard steel.

How is the box of 12,000 pieces packaged?

The 12,000 pieces are shipped in a box suitable for wholesale shipping. Bulk packaging is used; it is practical for production lines and factory stock.

What is the difference between a drill bit screw and a standard screw?

Standard screws require pre-drilling; drill bit screws create their own hole. This significantly reduces working time and cost, especially in metal applications. It also provides fast mounting in wooden applications.
