Carbon Steel Pozi Flat Head Half Thread Chipboard Screw Zinc Plated Rohs
|
Product Description
Chipboard Screws, as the name suggests, these screws can be used when doing general DIY work with chipboard and other softer types of woods. Unlike the Cut screws, they do not have the Type 17 cutting point and, therefore, require pilot holes, drilled 2mm smaller than the size of screw used. A Pozi screwdriver bit is then required to drive the screws home, but care must be taken as they have a tendency to slip and strip.
Countersunk or flat head
Conical, with flat outer face and tapering inner face allowing it to sink into the material. The angle of the screw is measured as the full angle of the cone.
Smooth shank version
Used when fixing wood to wood. The smooth shank part of the screw allows it to spin in the top piece of wood and at the same time pull the bottom piece tightly against the top piece, thus leaving no gap between the two. The smooth shank also prevents the screw head from pulling into the top piece of wood while it is driven into the bottom piece.
Raw Material: Carbon Steel
Carbon steel is a steel with carbon content up to 2.1% by weight.
The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance.
Case hardening processes harden only the exterior of the steel part, creating a hard, wear resistant skin (the "case") but preserving a tough and ductile interior.
Plating and Coatings
In the final step of manufacturing, most steel wood screws receive some kind of plating (a metallurgical process done to bare metal screws) or coating (applied to either bare metal screws or already-plated screws).
