FAQ

Selection-related

Q1: What are the size range and strength grades of BOLT bolts? How can one make an accurate selection?

A1: The size range covers M3 to M64 of all specifications. M3 to M12 is suitable for precise scenarios, M14 to M36 is suitable for general scenarios, and M39 to M64 is suitable for heavy-load scenarios. The strength grades cover 4.8 to 12.9 levels. 4.8 level is suitable for ordinary light loads, 8.8 level is suitable for general industries, and 10.9 to 12.9 levels are suitable for heavy-load and harsh working conditions. The selection needs to be combined with the application industry, the force situation, and the environment.

Q2: What are the differences in application scenarios for carbon steel, stainless steel, and alloy steel bolted parts?

A2: Carbon steel bolts have high cost-effectiveness and are suitable for indoor dry ordinary fastening scenarios; stainless steel bolts are corrosion-resistant and are suitable for humid, outdoor, and coastal environments prone to corrosion; alloy steel bolts have high strength and anti-fatigue properties, and are suitable for heavy-load, high-vibration industrial scenarios (such as construction machinery, rail transit), and can be selected as needed.

Technical-related

Q3: What are the core advantages of BOLT bolt's anti-loosening design and which scenarios are they suitable for?

A3: It adopts multiple anti-loosening schemes, which can effectively resist the loosening of bolts caused by equipment vibration and mechanical impact, reducing maintenance costs. It is mainly suitable for vibration-prone scenarios such as automotive manufacturing, rail transit, and mechanical equipment.

Q4: What are the usage precautions for high-strength grades (10.9/12.9 levels) of bolted parts?

A4: They are suitable for heavy-load and high-bearing capacity scenarios. When using, the preload should be controlled to avoid overload breakage; after electroplating, hydrogen removal is required, and outdoor use requires an anti-corrosion coating to prevent stress corrosion breakage.

Procurement and Customization-related

Q5: Are there in-stock bolted parts of regular specifications? What is the delivery cycle?

A5: Regular-sized bolted parts of M3 to M64, regular strength grades of 4.8 to 12.9, common materials, and surface treatments are all in stock. After placing an order, the goods will be dispatched within 1-3 working days. Bulk purchases can enjoy discounts.

Q6: Can non-standard-sized bolted parts be customized? What is the customization process and cycle?

A6: We can undertake non-standard customization. We support personalized customization of size, strength, material, etc. The process is: provide parameters to the engineer → engineer evaluation → quotation and sample production → confirmation of production. The cycle is 5-10 working days (adjusted according to the difficulty of customization).

Industry and Environment Adaptation-related

Q8： Which core industries are BOLT bolted parts suitable for？ Are there exclusive solutions for each industry?

A8： It is suitable for six core industries： automotive manufacturing， home appliances and electronics， building steel structures， mechanical equipment， new energy， and rail transit. We provide exclusive solutions for each industry's working conditions.

Q9： Are there special protection measures for bolted parts used in outdoor/high-temperature environments?

A9： There are dedicated protection schemes： for outdoor use， stainless steel + hot-dip galvanizing/anti-corrosion treatment is selected； for high temperature (≤500℃)， heat-resistant alloy steel + high-temperature coating is selected； for low temperature (≤-70℃)， low-temperature-specific materials are selected. Customization can be done as needed.
