Timco 4.8 x 40 Baypole Screws – Product Details
These screws feature a wafer flange head that offers a wide bearing surface to help distribute load and reduce pull-through in frame materials. The PH (Phillips) drive ensures secure bit engagement, while the self-drilling point eliminates the need for pre-drilled pilot holes in many applications — saving installation time on site.
Manufactured from hardened carbon steel with a zinc-plated finish, these screws offer corrosion resistance suitable for internal and sheltered external environments. Supplied in a pack of 200, they are ideal for baypole fixing, frame joining and specialist glazing work.
