SCREWS

A screw is a mechanical fastener with a helical ridge, commonly known as a thread, wrapped around a cylindrical shaft. It is designed to be inserted into materials by rotating it with a tool such as a screwdriver or wrench. The unique design of a screw allows it to hold objects together securely or position materials with precision. By creating a clamping force, screws resist loosening even under vibration, making them reliable for a wide range of applications in wood, metal, plastic, and composite materials.

TYPES OF PUNCHES

In screw making, punches are essential tools used to create precise indentations, marks, or shapes on screw blanks and heads. They help in forming slots, embossing head designs, or preparing surfaces for further machining. Punches are typically made of hardened steel to withstand repeated impact without deformation. They ensure accuracy, consistency, and alignment during production. By guiding the placement of threads or head features, punches enhance the efficiency of automated or manual screw manufacturing, contributing to the uniformity, functionality, and quality of the final screws.
