DIN912 Socket Head Cap Screws M1.4 M6 Stainless Steel A2-70 Grade Hex Head Type Plain Finish Bulk Supply

Hexagon head bolt Stainless steel is corrosion-resistant

The stainless steel hex socket bolts are made of high-quality 304 stainless steel, which is corrosion-resistant and heat-resistant, and are 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 inner hole needs to be installed in conjunction with an Allen wrench or socket tools (such as a box wrench). 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, 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 and engineering, electronics and electrical appliances, and pipeline systems.

Recommended tools: Allen wrench, electric screwdriver, torque wrench (for controlling preload).

Precautions: Avoid over-tightening to prevent thread slippage or component deformation.

Standard torque value: Determined based on the bolt diameter and material (for example, the torque of an M8 stainless steel bolt is approximately 25-35N·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 chemical corrosion. Reapply anti-rust grease if necessary.

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