What does BZP mean bolts?

BZP (Bright Zinc Plated) is a process that takes place in the manufacturing stage of the fixing at which point the standard steel or alloy product is coated with a thin layer of zinc using electric currents, to offer galvanising protection to the steel and prevent rusting or oxidation.

What does A2 mean on a bolt?

DIN/ISO A2 Stainless Steel Is A Corrosion Resistant Steel; It Is Also Known As ASTM-304. A2 / ASTM-304 Is An 18/8 Stainless Steel : This Designates A Metallurgical Content Of 18% Chromium & 8% Nickel. A Bolt Marked A2-70 Is A 304 Stainless Steel Bolt With A 700 N/mm2 Tensile Strength (See Below Table).

What is BZP finish?

BZP (Bright Zinc Plated) Fasteners Bright Zinc Plated is a finish applied to metals such as carbon steel, unalloyed steel and cast iron. It is the most common fastener finish and provides a thin layer of protection against rust and oxidation.

Is A2 stainless steel any good?

A2 grade stainless steel is also often referred to as type 304 or 18/8 – this latter label denotes the fact that A2 grade stainless steel containing approximately 8% nickel and 18% chromium. With a high hardness level and consistent dimensional stability, A2 stainless steel shows good resistance to wear & tear.

Is galv the same as BZP?

Zinc plating (also known as electro-galvanising) is a process where zinc is applied by using a current of electricity. While is does provide some rust protection, its thinner coating is not as rust resistant as hot dip galvanising. Its main advantage is it is cheaper and easier to weld.

Are 8.8 bolts high tensile?

High tensile steel bolts Grade 8.8 high tensile steel is often referred to as the structural grade for bolts. It is the most common form of high tensile material and is usually stocked in plain finish or zinc. It can be plated in many other coatings.

What bolt size is A2?

Manufacturer of A2 70 Bolt Material according to standard, Check A2-70 Bolt Size Chart

Is A4 stainless stronger than A2?

A2 vs A4 stainless steel strength Whereas grade A4 is stronger than grade A2, and its tensile properties are almost similar to alloy steel grade 8.8.

What does A2 stainless steel mean?

A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy – 18% chromium and 8% nickel. A2 (304, 18/8) is an austenitic steel and is non-magnetic. The chromium provides a corrosion and oxidation resistance, however it can tarnish.

What is A2 stainless equivalent to?

SAE 304
SAE 304 is a standard grade of stainless steel, suitable for most applications. SAE 304 is an equivalent to A2 stainless steel.

Is A2 or A4 stainless steel better?
