Hex Head Self Tapping Screws 3/8 5/16 Stainless Steel For Metal

What Are Hex Head Self-Tapping Screws?

Hex Head Self-Tapping Screws are threaded fasteners with a hexagonal head designed to create their own mating threads when driven into materials like metal, plastic, or wood. Unlike standard screws, they eliminate the need for pre-drilled holes, making them ideal for quick and secure fastening.

Materials of Hex Head Self-Tapping Screws

Hex Head Self-Tapping Screws are available in various materials, including:

Carbon Steel (Low/Medium/High Strength)
Stainless Steel (304, 316 for corrosion resistance)
Alloy Steel (Heat-treated for high strength)
Aluminum (Lightweight applications)

Surface Treatments (Coatings)

Common coatings for durability and corrosion resistance:

Zinc Plating (Standard corrosion protection)
Black Oxide (Aesthetic & mild corrosion resistance)
Galvanized (Hot-dip or electroplated for harsh environments)
Phosphate Coating (Improves paint adhesion & wear resistance)
Dacromet/Geomet (High corrosion resistance)

Common Sizes & Specifications

Applications

Metal Fabrication (Sheet metal, HVAC, automotive)
