Why are there 2 different types of screwdrivers?

The reason for the different styles is cost and torque. Phillips screws are self-centering, making powered screwdrivers possible. They’re somewhat more expensive to produce than slotted-head. They tend to ‘cam-out’ easily under torque, making it hard to apply much torque.

Why are there flat head screws?

The most common sizes are #2 and #1, #2 for standard screw sizes, #1 for “miniature”. Phillips head screwdrivers are designed to “cam out”, which means they are designed to slip out of the screw, so you don’t over-tighten them.

What is flat head screwdriver?

A flat-head screwdriver is a screwdriver with a wedge-shaped flat tip, used to tighten or loosen screws that have a straight, linear notch in their heads. This is arguably the most common tool on the planet—the ubiquitous flat-head screwdriver.

What is flat head screw?

Flat Head Screws, also called Countersunk Screws, are conical with a flat outer face and a tapering inner face.

These screws are commonly made out of stainless steel or zinc coating.

Why are there so many different types of screwdriver heads?

The reason for the different styles is cost and torque. The slotted head screws are cheap and easy to make. But they’re completely useless for powered screwdrivers and you can’t put much torque on the screw without it either slipping out or stripping the head (and maring the surface of whatever you’re screwing).

What is the difference between Robertson and Phillips screw drives?

For example, the Robertson screw drive is much more resistant to slipping, which is a serious issue with slotted head screws. They are also much less likely to strip, which is a problem for Phillips screw drives.

What is the difference between Slotted head and Phillips head screws?
