PC Screws Cross Slot Drive Flange Head Carbon Steel White Zinc Plated Supplier

PC screws have a uniform diameter the entire length of the shaft as opposed to tapered screws that have a pointed tip. They are used to fasten machine components, appliances, and more. Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers. Ever Hardware provides custom-made fasteners and customizable packaging.

The slot screw drive has a single slot in the fastener head and is driven by a “common blade” or flat-bladed screwdriver. It was the first type of screw drive to be developed, and for centuries it was the simplest and cheapest to make. The slotted screw is common in simple woodworking applications but is not often seen in applications where a power tool would be used because a power driver tends to slip out of the head, potentially damaging the surrounding material. The tool used to drive a slot is called a common blade, standard, flat-blade, slot-head, flat-tip, or “flat-head/flathead” screwdriver.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent pc screws rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion-resistant, multi-layered coating of zinc-iron alloy and zinc metal.
