Product Description

Product Name  304 Stainless Steel Hex Head Bolts
Material  Made from 304 stainless steel, these screws have good chemical resistance and may be mildly magnetic. They are also known as A2 stainless steel.
Head Type  Hex Head.
Length Is measured from under the head.
Thread Type Coarse Thread, Fine Thread. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
Standard Screws that meet ASME B18.2.1 or formerly DIN 933 specifications comply with these dimensional standards.

Application

Stainless steel hex bolts find extensive applications across various industries due to their corrosion resistance, strength, and durability. The hexagonal head allows for easy tightening with a wrench or socket. Here are some common applications for stainless steel hex bolts:

Marine Applications:
Stainless steel hex bolts are resistant to corrosion, making them suitable for use in marine environments for boat construction and repairs.

Oil and Gas Sector:
Hex bolts are utilized in the construction and maintenance of oil rigs, pipelines, and other infrastructure in the oil and gas industry.
