ASTM A320 L7M Stud bolt HDG Hot Dip Glavanized Hext nuts manufacturer in China Standard: ANSI/ASME B 18.31.2,DIN975/DIN976, Diameter: 1/4"-5",M6-M125 Length: ≤9m or 30feet Material: ASTM A320 L7M stud bolt
A stud bolt is a type of fastener commonly used in industrial and construction applications. It consists of a threaded rod with threads on both ends An full set of stud bolt connections is usually consisited with 2 Hex nuts and the stud. Sometimes, washers and additional nuts may be used. In high-pressure piping and pipeline flange connections, stud bolts are widely used.
Ceramic SermaGard 1105 + PTFE SermaGard 1280 Coated Stud bolt
Our Stud bolt and nuts can be applied with Fluoropolymer/Ceramic coating system The base coat applied a Ceramic coating,utilizes an extremely hard ceramic matrix alloy know as xylar 2 ,which provides exceptional corrosion and abrasion resistance to the fastener. The fluropolymer PTFE xylan topcoat is designed to ensure that the threads remain permanently dry-lubricated, making torqueing up easier and preventing subsequent corrosion seizure.
ASTM A320 B8M Stud BOLT and A194 8M HEX NUTS,Grade B8M Stud Bolt is made from 316 stainless steel, a type of fastener designed for use in pressure vessels, flanges, valves, and other high-stress applications, particularly in environments where corrosion resistance and low-temperature toughness are critical.
China Professional manufacturer of PTFE Xylan Coated HEX BOLT SS316 A4-70 ISO4017 An A4 hex bolt also known as SS316 Hex bolt, refers to a hexagonal-headed bolt made from A4-grade stainless steel, which is highly resistant [...]
Xylan 1424 Coated Stud Bolts are fasteners coated with Xylan 1424, a high-performance fluoropolymer coating that provides outstanding protection against corrosion, friction, and wear. This makes them ideal for use in harsh environments where durability and long-term performance are critica
Zinc Nickel + PTFE Xylan 1070 Coated Stud bolts A194 B7 order spec Product Name: Zinc Nickel + PTFE Xylan 1070 COATED Stud bolt and Nuts Standard: ASME B18.31.2 Material for Stud Bolt: Alloy Steel ASTM A193 Grade B7 Material for Nut: ASTM A194 Grade 2H Parts: with Two Heavy Hex Nuts Surface Treatment: Zinc Nickel Plating + Xylan 1070 Blue coating
Stud bolts manufactured to ASTM A193 Grade B7 and B7M are widely used in high-temperature and high-pressure applications such as refineries, chemical plants, and power generation facilities. While these grades share similarities, they have important differences in mechanical properties, hardness, and application suitability.So when engineers select the material for stud bolt,they should consider which one is more suitable for the projects
When you make decision between ASTM A320 Grade L7 and L7M stud bolts, consider the environmental conditions and specific application requirements. Grade L7 is ideal for strength and toughness in cryogenic systems, while Grade L7M excels in environments where corrosion resistance and reliability are critical.
