Self Tapping Screws, Taptite High Tech Screws

This is a category page for tapping screws, Tap-Tite and high-tech screws. For MISUMI, you can select from nominal of 1.2 to 8, length of 2 to 200 mm, 8 types of mount hole shape, 3 types of material and 21 types of surface processing.
In addition to the normal shape, we offer flanged products and those with built-in washers.

[What is a tapping screw?]
It is a screw to be tightened while threading itself against the pilot hole to be tightened. It eliminates the need for tapping, which leads to reduced work costs.
As screws themselves perform threading, the fastening force is high and it does not easily get loosened, but it also has the disadvantage of being difficult to remove.
Types 1, 2 and 3 are available, which are used according to the materials to be tightened.

Product Overview

Self-tapping screws are fastening components designed to form internal threads directly into a pilot hole during installation, eliminating the need for pre-tapping. This significantly reduces assembly time, tooling requirements, and labor costs while ensuring strong and reliable fastening.

Types of Self-Tapping Screws

Self-tapping screws are classified based on thread-forming behavior and application material:

Type 1, 2, and 3: Selected according to the hardness and thickness of the base material
Tap-Tite Screws: High-performance thread-forming screws that provide consistent torque control and reduced installation stress
Self-Drilling Screws: Equipped with a drill-point tip for thin metal fastening
Flanged and Washer-Integrated Types: Improve load distribution and reduce the need for additional components

Head Shapes and Drive Types

Available in multiple mounting hole shapes, including pan head, countersunk, hex head, and other drive configurations to match torque requirements and space constraints.

Applications

Self-tapping and Taptite screws are widely used in:

Sheet metal assemblies
Plastic and resin components
Electrical enclosures
Automotive and appliance manufacturing
Industrial equipment and general fabrication

Key Advantages

No tapping process required
High fastening force and reduced loosening
Wide size range and configuration options
Suitable for automated and manual assembly

Usage Notes

Due to their thread-forming nature, self-tapping screws can be difficult to remove once installed. Proper size selection, pilot hole preparation, and torque control are essential to prevent material damage and ensure optimal performance.
