Hexagon head bolt Stainless steel is corrosion-resistant

Stainless steel hexagonal bolts are made of high-quality 304 stainless steel, which is corrosion-resistant and heat-resistant, and suitable for most industrial scenarios. The tensile strength can reach 800-1100MPa, making it suitable for high-load scenarios. It has a wide operating temperature range (-60℃ to +600℃) and is suitable for extreme environments. The hexagonal structure facilitates the application of torque with tools such as open-end wrenches and box wrenches, making it suitable for scenarios requiring high-torque fastening. Thread specifications include metric (M), such as M4×20 (diameter 4mm, length 20mm), and imperial (UNC/UNF), such as 1/4 "-20" (diameter approximately 6.35mm, 20 threads per inch). The length and type are standard types, and the thread runs through the entire length (full thread).

Semi-threaded type: Only the end is threaded, and the head is a smooth cylinder. It is suitable for scenarios that require a larger support area. Mirror polishing, beautiful and corrosion-resistant; The application scenarios are applicable to solar photovoltaic brackets, industrial machinery, construction projects, electronic appliances, pipeline systems, etc.

Recommended tools: It is recommended to use a socket wrench or an adjustable wrench. Avoid using a box wrench to apply excessive force, which may cause deformation of the hexagonal surface

Standard torque value: Determined based on the bolt diameter and material (for example, the torque of an M8 stainless steel bolt is approximately 25 to 35n·m).

Anti-loosening measures: Use spring washers, thread sealants or self-locking nuts to prevent loosening due to vibration.

Regular inspection: Check the fastening condition every six months in harsh environments.

Cleaning and maintenance: Wipe the surface with a soft cloth to avoid corrosion by chemical substances. Reapply anti-rust oil if necessary.

International standards: ISO 7380 (Stainless steel bolts), DIN 933, ANSI B18.2.1. Other standards can be customized according to customer requirements

Applicable to a variety of application scenarios
