Product Features:
Material: 304/316 Stainless Steel
Size: M10x35
Applications: Heavy machinery and equipment: Components that require rust prevention or frequent disassembly
Construction/Decoration Industry: Outdoor structures, stainless steel guardrails, etc.
Marine/Chemical Industry: High-corrosion environments
Food Industry: Equipment with high hygiene requirements
Advantages: Strong corrosion resistance, naturally resistant to rust, suitable for humid, acidic and alkaline environments, longer lifespan than ordinary carbon steel bolts, no need for additional coating, avoiding corrosion problems caused by coating peeling.
Head design, easy to install, the square head can be tightened with a regular open-end wrench or adjustable wrench, no special tools required, convenient for manual operation. The head design is suitable for manual adjustment or temporary fixation, providing greater flexibility during maintenance.
Hygienic and aesthetic, stainless steel is non-toxic and odorless, meeting the hygiene standards for food and medical equipment. The matte or polished surface is suitable for decorative applications in exposed areas.
Low maintenance cost, maintenance-free, stainless steel is resistant to aging, no need for rust prevention treatment during long-term use, reducing maintenance frequency and cost.
Material Certification: Confirm the 304/316 marking and material report.
Size Matching: Measure the width of the head across the flats, the diameter of the thread, and the length.
Strength Grade: The strength of stainless steel bolts is typically A2-70 (304) or A4-80 (316), with the number indicating the tensile strength (e.g., 700 MPa).
For dynamic load applications, consider anti-loosening measures.
For heavy load applications, it is recommended to use alloy steel material.
Common Issues: Risk of stripping: The square head may slip under excessive force. It is recommended to use an appropriate wrench.
Anti-loosening Measures: May be combined with nylon lock nuts or thread lock adhesive.
Packaging: Default is bulk wholesale.
Available options: (Carton + pallet) (Carton + wooden pallet)
FAQ
Q1: How much difference is there in corrosion resistance between 304 and 316 stainless steel square head bolts? Which one is more suitable for use in the seaside?
A1: The 304 stainless steel material is resistant to weak acids, weak alkalis and common atmospheric corrosion, and is suitable for daily environments. The 316 material contains molybdenum and is resistant to salt fog and seawater corrosion, making it suitable for marine or industrial environments.
Q2: What torque is required for installing the square head bolts? Will over-tightening cause the corners to wear down?
A2: The torque control for the square head bolts needs to be determined based on the strength grade of the material and the size of the bolt. Over-tightening may cause the threads to slip, and the square head to be subjected to concentrated force, resulting in the corners being prone to deformation.
Q3: Do stainless steel square head bolts support non-standard customization (such as adding longer threads)?
A3: Yes
