Zhuocheng Stainless Steel Shoulder Phillips Slot Screw

The Phillips screw is more commonly used than a slotted screw because it's more stable with four contact points. The Phillips drive design was made to perform better with screwdrivers.

Shoulder Socket Cap Screws are high strength fasteners with an Internal Hex or Allen drive style head. The shoulder is a cylindrical unthreaded area before the thread, allowing for rotation of parts and are used in moving parts and other mechanical applications.

The slotted design makes them easy to install, and they can be removed without damaging the threads or the surrounding surface. Round head slotted machine screws have excellent threading that facilitates a firm and secure hold, enhancing safety and reliability.

This self-centering design of Philips head screws allows the screwdriver to apply a significant amount of torque to the screw without slipping out of the head – a common problem with slotted flat head screws, which feature a single slot, or groove, on the head. Phillips screws are mostly used in electronics, automotive and construction.
