Stainless steel screw

 Hex Allen Bolts Factory A2-70 A4-80 Cylindrical Head Stainless Steel Socket Head Cap Screws (DIN 912)

This series of products are made of high-quality stainless steel 304 or 316 through cold forging. They undergo precise threading process, with uniform and smooth thread pitches, strong locking force and low risk of loosening. The head features a cylindrical knurled design, enhancing friction and facilitating easy insertion by hand. It is equipped with an internal hexagonal driving groove, providing a large contact area and reducing the risk of damage during tightening, making it suitable for high-strength fastening connections. The products comply with ISO/DIN standards, have a complete range of specifications, and support non-standard customization.

Regarding the production of screws, we are experts.

We are a professional China screws manufacturer with over 15 years of deep expertise in the fasteners factory industry. Our diverse product portfolio covers mainstream categories, including 304 stainless steel screws, self tapping screws, self drilling screws (Tek screws), machine screws, wood screws, as well as eye screws and hex bolts.
Strictly compliant with DIN, ANSI, BS, and JIS international standards, our products are available in a full range of drive types, including Phillips, Pozi, and Torx drives. We also offer comprehensive custom screws services tailored to your specific requirements. Leveraging our competitive factory direct price and fast delivery advantages, we proudly serve as a reliable China supplier for global wholesale hardware distributors, engineering procurement managers, and OEM clients seeking high-quality bulk screws. We are committed to providing free samples available for your testing needs, and all our products fully comply with RoHS and REACH environmental standards.

Introduction to Main Business Scope

Our company mainly deals in various stainless steel and carbon steel fasteners and hardware accessories. Our product range includes self-tapping screws, machine-drilled screws, hexagonal bolts, expansion screws and non-standard customized hardware parts. These products are widely used in industrial and civilian fields such as photovoltaic new energy, building curtain walls, automotive manufacturing, electronic communication and outdoor furniture, and we also support custom orders based on drawings.

Features

Selected high-quality stainless steel, not recycled material from secondary production, with pure material.

Characteristics: High corrosion resistance, high oxidation resistance, not prone to rust, long service life.

Applications: Outdoor equipment, bathrooms, marine environments and other high-demand scenarios.

Precision thread processing

The head features anti-slip rolling patterns, which enhance the friction between the fingers and the surface.
Advantages: It is easier to apply force during installation, facilitating quick pre-positioning and manual pre-tightening, thereby improving work efficiency.

The slot is deep and regular, with precise diagonal dimensions.
Advantages: When used with an internal hexagonal wrench, it provides strong torque transmission, distributes force evenly, and completely eliminates the problem of "slipping threads".

Using the fully automated cold heading threading technology, there are no burrs or ragged teeth.
Advantages: The threaded parts pass the thread gauge inspection, are easy to screw in, have a tight fit, and have excellent anti-loosening performance.

Pro Test Data

Salt spray test: For 304 material, no red rust for ≥ 72 hours; for 316 material, no red rust for ≥ 200 hours (with Dacromet coating, it can reach 500 hours+).

Torque test: The destructive torque of M5 304 self-tapping screws ≥ 8.0 N.m, meeting the GB/T 3098.6 standard.

Hardness test: The hardness of the self-drilling tail can reach HRC 50-55, ensuring worry-free penetration of high-hardness thin plates.
