Structural Screws Vs Lag Bolts Screws
Content
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean
An define of the range of stainless steel fasteners out there in Australia may be found in the Australian Stainless Reference Manual. One frequent false impression about stainless steel bolts is that they are stronger than bolts manufactured from carbon steel. Due to a low carbon content, chrome steel cannot be hardened, which makes these bolts significantly weaker than a hardened steel bolt.

Fasteners which were zinc plated have a shiny, silvery or golden look, known as clear or yellow zinc respectively. They are fairly corrosion resistant but will rust if the coating is destroyed or if exposed to a marine setting. Grade 8 bolts have been hardened greater than grade 5 bolts. Thus they’re stronger and are utilized in demanding functions corresponding to automotive suspensions.

A 12.9 bolt is one of the highest grade of bolts produced. Known for their excessive tensile power, they’re constructed with both hex and Torx heads and can be found in zinc or chrome finishes.
- A stainless steel bolt has the identical PSI rating as a grade 5 bolt .
- A frequent question is whether or not stainless steel is stronger that a grade 5 or grade 8 bolt.
- Stainless steel bolts are rated for corrosion resistance.

These products are built to final and work optimally under harsh usage and must be easily identifiable by way of a permanent marking on the pinnacle to permit the customer to distinguish them. Generally these are produced from grade 304 , grade 316 or for less demanding purposes, grade 303 . Grade classifications A 1, A2 and A4 are in accordance with International Standard ISO 3506; head markings typically present this classification. It is widespread follow and legitimate to manufacture objects labelled as grade 304 from grades 302HQ or 304 relying on the type of fasteners and the manufacturing process. Less commonly, fasteners are available in hardened and tempered martensitic stainless steels, corresponding to 410 or in a higher molybdenum model of grade 316, often designated ‘2343’.
Grade 8.8 excessive tensile steel is also known as the structural grade for bolts. It is the most typical form of high tensile materials and is usually stocked in plain end or zinc. It could be plated in many different coatings.For excessive tensile steel grade 8.8, a torque wrench will be required for the tightening of mentioned product.
Reasonable care should be taken when handling chrome steel fasteners to keep away from any thread harm and maintain the threads clear and free from dust, coarse grime or sand. If the threads are tightened on sand or dust the possibility of galling or seizing is elevated.

Are higher grade bolts more brittle?
The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
With good formability, 304 stainless steel may be readily welded by all common methods. Fasteners are manufactured in a wide range of materials from widespread steel to titanium, plastic and different unique supplies.
