Truss head refers to a screw head that is extra wide and has a slightly rounded surface, or top. In other words, the head or top on the screw protrudes just above the surface to be fastened but contains a wider surface area just under the head.
These screws can be used for applications like securing thin membranes, such as one-ply, through insulation. Wooden truss head screws are also commonly used to attach cabinets to steel studs; or to attach sliding shelf supports, since the low-profile head of the truss head screw does not interfere with guide operation.
Truss head screws are well suited for sheet metal and other material with large diameter holes due to their wide head. Additionally, because of their low-dome shaped head, these screws make tampering with or removing the head difficult.
Anodizing (also spelled anodising, particularly in the UK, India and Australia) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
The process is called anodizing because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.
