Captive Screws - Inch Metric Captive Screw - PIC Design

Captive Screws feature a shoulder under the head that is smaller in diameter than the root of the thread.This allows the screw to be captured between the head and threaded end when screwed into a plate with a threaded hole.The shoulder ensures that the screw will not fall out and be lost during disassembly or maintenance and prevents screws 36 Types of Screws and Screw Heads (Ultimate Chart Guide)Tri-Wing screws are a somewhat recent invention of the Phillips Screw Company,which offer both the ability to apply more force than you could to a regular Phillips screw and more security than other screws.The Tri-Wing design needs a special driver to install and remove it,and its deep grooves allow for more torque from a drill.1/4-20 Thread Forming Screws - Thread Cutting Screws Use a thread cutting screw or a thread forming screw to create a tight fit in heavy gauge sheet metal,aluminum,cast iron and other hard materials.Both are a type of self tapping screw.Thread cutting screws have tapered entering threads and multiple cutting edges to dig into the boss (tapped hole).
