Stainless Steel Non-Standard Screws

Product Description

The 304 stainless steel hex socket lockable adjusting bolt consists of two stainless steel hex socket bolts and a hex socket nut. It achieves locking by being tightened against each other and is used for adjusting clearances, fixing positions, or preventing loosening. This type of bolt is typically employed in concealed adjustment structures of high-end furniture and as fasteners in mechanical structures, suitable for applications requiring corrosion resistance and high strength.

Application Scenarios

Industrial Equipment: High-precision assembly of machine tools, pumps, valves, conveyor belts, etc.

Automotive Manufacturing: Engine components, chassis fastening (anti-rust + anti-vibration)

Electronics and Electrical Appliances: Circuit board fixation, enclosure assembly (counterbore design to prevent hand scratches)

Medical Equipment: Surgical instruments, imaging equipment

Marine/Chemical Industry: Pipeline flanges, offshore platforms

Features

Material: 304 Stainless Steel A2, resistant to general acids, alkalis, and humid environments, suitable for indoor equipment and general industrial applications.

316 Stainless Steel A4, containing molybdenum, resistant to seawater, salt spray, and chemical corrosion, suitable for ships, chemical industries, and coastal facilities.

Hygiene and Safety: Non-toxic and pollution-free, meeting food-grade and medical equipment standards.

High Temperature Resistance: 304 can withstand temperatures up to about 800°C, while 316 can withstand even higher temperatures up to 900°C, suitable for high-temperature environments such as boilers and thermal pipelines.

Size: M10x50 (OEM/ODM custom sizes available)

Advantages

Corrosion-resistant and high-temperature resistant.

Good anti-loosening performance, less likely to fall off in vibrating environments.

Stainless steel material requires no maintenance and has a long service life.

High torque capacity.

Precautions: Avoid excessive torque that may cause thread stripping.

For enhanced rust resistance, 316L material is recommended.

Anti-loosening measures: In vibrating environments, it is recommended to pair with lock nuts.

Packaging: Default bulk wholesale (can be packed in cartons on pallets)

Available options: (Cartons + Pallets) (Cartons + Wooden Pallets)

FAQ

Q1: Will stainless steel hexagonal screws attract magnets?

A1: 304/316 usually do not attract magnets. After cold processing, they may have weak magnetism. If complete magnetism-free is required, 316L is the preferred choice.

Q2: How about the anti-loosening performance of the lock bolts? Do additional measures need to be taken?

A2: Their self-anti-loosening performance is average. It relies on the preload of the two end threads.

Q3: What is an anti-lock screw?

A3: It is a fastener with hexagonal drives at both ends, usually used for high-precision alignment and fixation between two components.
