JIS Screw Cross Slotted Head Copper Fasteners Pozidriv Custom Bolts
The JIS screw is commonly found in Japanese equipment. It looks like a Phillips screw, but is designed not to cam out and will therefore be damaged by a Phillips screwdriver if it is too tight. Heads are usually identifiable by a single dot or an “X” to one side of the cross slot. Ever Hardware provides the custom-made JIS screw and customizable packaging.
The Pozidriv is an improved version of the Phillips screw drive. Pozidriv was jointly patented by the Phillips Screw Company and American Screw Company. The name is thought to be a portmanteau of the words “positive” and “drive.” Its advantage over Phillips drives is its decreased likelihood to cam out, which allows greater torque to be applied. In ANSI standards, it is referred to as “Type IA.” It is very similar to, and essentially compatible with, the Supadriv screw drive.
Pozidriv drive bits are often designated by the letters “PZ” plus a size code of 0, 1, 2, 3, 4 or 5 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
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.
