Half Thread Stainless Steel Hex Head Bolt
This half thread hex bolt is a corrosion-resistant precision fastener, specially developed for humid, marine and weakly corrosive working environments.
It is integrally manufactured from SUS304 stainless steel, with natural metallic polished surface without any electroplating coating, maintaining stable long-term anti-rust performance. The half-thread structure consists of a smooth polished unthreaded shank and precise partial rolling thread, which can pass through thick stacked plates and cooperate with standard stainless steel hex nuts to form uniform compression clamping.
The regular hexagonal head matches socket wrenches and torque tools, realizing convenient and slip-free tightening operation. A2-70 grade stainless steel provides reliable tensile and shear bearing capacity, which can meet the fastening demands of medium load precision equipment.
Compared with carbon steel hot-dip galvanized bolts, stainless steel bolts have permanent anti-corrosion performance and will not lose anti-rust effect due to coating peeling. It is widely used in marine, food, chemical, coastal new energy and precision automation industries. All finished bolts pass hardness, tensile strength and thread precision inspection before delivery, complying with international stainless steel fastener standards. Custom overall lengths and special material specifications can be produced for bulk export orders.
