As a manufacturer based in China, we are dedicated to providing merchants from all over the world with high-quality products that will help them achieve success. With that in mind, let's take a closer look at the features and benefits of our steel hex screws.
Premium Material for Optimal Performance
First and foremost, our steel hex screws are made of premium-quality materials that ensure optimal performance. Our screws are made of carbon steel, which is known for its strength and durability. It is also corrosion-resistant, making it an ideal material for screws that will withstand exposure to the elements. In addition, our screws are heat-treated to achieve a hardness of 12.9 on the Rockwell hardness scale, which means that they're able to withstand high-stress environments without losing their shape or strength.
Precision Manufacturing for Tighter Fits
Another benefit of our steel hex screws is that they're manufactured with precision to ensure a tight and secure fit. The hex-shaped head provides more surface area for the screwdriver to grip, which reduces the likelihood of slippage or stripping. The threads of our screws are also cut with precision, ensuring that they fit tight and securely into the intended surface.
Versatile Design for Numerous Applications
Our 12.9 Steel Hex Head Screws are designed with versatility in mind, making them ideal for a wide range of applications. They're commonly used in construction, automotive, manufacturing, and DIY projects. The hex head also makes them ideal for use in machinery or equipment that requires frequent disassembly and reassembly.

Whether you need a few screws for a quick repair or a large quantity for a major project, we have you covered. Our sizes range from M2 to M48, with lengths ranging from 3mm to 400mm.

Product description:
Metric 12.9 Steel Hex Head Screws and Hex Bolts have the highest tensile strength compared to Grade 9. These fasteners are used in machinery and large equipment under heavy stress.
Choose these 12.9 Steel Hex Head Screws for heavy-duty stamping applications and earth-moving machinery like bulldozers and excavators. With a tensile strength of 170,000 psi, they are 10% stronger than our other metric steel screws. Dimensions conform to ISO 4017 (formerly DIN 933). The length is measured from the head down.
Zinc-plated yellow chromate steel screws resist corrosion in wet environments.
Features:
Bolts are externally threaded fasteners with heads used to hold two objects (usually metal or wood) in a fixed position relative to each other.
The screw cuts its own thread, and the bolt mates with the internal thread of the nut to hold in place and ensure the different desired tension levels in the bolted connection.
Use nuts to aid in disassembly and reassembly. Also, bolts generally have greater load-carrying capacity than screws, but lack a tapered shaft. The head style of the bolt determines the tool required for tightening and loosening.
Bolts are responsible for holding everything together, from furniture to machinery to bridges.
