Stainless Steel Self-Tapping Screw

A stainless steel self-tapping screw is a fastener made of stainless steel. It consists of a threaded shank and a head for installation. It cuts its own thread inside the joined parts, without a pre-drilled hole.

Stainless steel self-tapping screws are produced in various types and are designed for installation in materials of different hardness — from loose to hard. The product size is denoted by two numbers: the first is the nominal thread diameter, the second is the overall length of the self-tapping screw. The more porous the material being joined, the greater the length of the product should be.

Self-tapping screws differ in size, thread pitch, head type, recess type and tip type. The tip can be blunt or sharp, and may also be fitted with its own drill point.

Applications

Stainless steel self-tapping screws are used in the food industry, furniture manufacturing, mechanical engineering, instrument making, aviation and other manufacturing and construction fields.

Features

Stainless steel self-tapping screws are manufactured to GOST, ISO and DIN standards. Food-grade stainless steel A2 or acid-resistant grade A4 is used. The material withstands high-temperature exposure up to several hundred degrees without deformation.
