Specifications

We have 3 sets of screw machines, we offer OEM screws, fasteners. At competitive price.

Materials:
Type 316 Stainless Steel— Our most corrosion resistant stainless steel. Withstands solvents and pitting caused by chloride and sulfur. It’ s a good choice for ACQ-treated (arsenic-free) lumber and may be mildly magnetic.
18-8 Stainless Steel— Has excellent corrosion resistance and is a good choice for ACQ-treated (arsenic-free) lumber. It may be mildly magnetic.
Type 410 Stainless Steel— Stronger than Type 316 and 18-8 stainless steel but less corrosion resistant. Magnetic.
Brass— Nonmagnetic with very good corrosion resistance. An excellent conductor of electricity, it’ s usually softer than steel and stainless steel.
Aluminum— It’ s nonmagnetic and one-third the weight of steel. Offers mild resistance to corrosion.
Steel— This low-strength general purpose metal is often plated with zinc for rust resistance.
 
Finishes:
Zinc Plated and Black Zinc-Plated— Enhances rust resistance. Black adds a decorative finish.
Black Oxide and Black Phosphate— Provides a dark look, adds mild rust resistance, and makes screws easier to thread.
Black Coated— Delivers corrosion resistance and deep, consistent color that won’ t rub off with repeated use.
Chrome Plated— Bright and attractive. Offers good rust resistance.
Nickel Plated— A decorative finish that’ s more rust resistant than zinc plating and less expensive than chrome plating.

PTFE Coated— This slick coating prevents fasteners from sticking and binding.

Weather-Resistant Coated— Resists corrosion better than zinc plating and minimizes reactions between dissimilar metals.
Hot-Dipped Galvanized— This thick plating provides superior rust resistance compared to zinc-plated steel. A good choice for ACQ-treated (arsenic-free) lumber.
