Button Head Bolt

Button head bolts are used all over the place,such as in cars (like engines and frames), construction (steel structures and roofs), and factory machines (conveyor belts and equipment panels). Their flat, rounded tops make them perfect for furniture, where bolts need to look nice and not stick out.

In wind turbines or solar panel setups, button head bolts handle rough weather while keeping things sturdy. Aerospace and boat builders love them because they don’t rust and stay tight even when things shake. Whether you’re building a bookshelf or a skyscraper, these bolts work in so many different situations.

Material

The type of material used for button head bolt really matters. For example, stainless steel 316 is great for boat parts or salty areas because it resists rust and acid. Carbon steel grade 10.9 is super strong (like 1,040 MPa strong) for high-stress jobs like bridges or heavy machinery. Alloy steel AISI 4140 is heated and cooled to make it tough enough for super hot or cold conditions. If you need non-magnetic bolts, they might use copper-aluminum mixes.

All materials go through tests like hardness checks and stress tests to make sure they work. The bolts also get tested for thread strength and how well they hold up when tightened, so they meet safety standards for things like cars, buildings, or planes.

FAQ

Q: What industries commonly use button head bolt, and why are they preferred?

A: Button head bolts are used in cars, buildings, planes, and green energy setups. Their flat, rounded tops don’t catch on clothes or tools in machines, and the wide flat part under the head spreads weight evenly to prevent breaks. In car engines, they can also tighten connections under severe vibration. In the construction industry, they can be used in places where bolts are needed, such as roofs or walls, to make them beautiful and firm.Aerospace uses lightweight titanium bolts to save fuel. Solar panel mounts use corrosion-resistant coatings to handle weather.

Button head bolts are versatile, meet global standards, and work in tough conditions.

Product Material

Button Head Bolt is mainly made of carbon steel and stainless steel, with some models using alloy steel for specific needs. Carbon steel is the most common material, cost-effective and hard enough for daily fastening scenarios like furniture assembly, electrical equipment fixing and light mechanical connections. It’s suitable for indoor environments where there’s no strong corrosion. Stainless steel, usually 304 or 316 grade, is used in humid places or outdoor settings, as it resists rust and corrosion better. Alloy steel is adopted for occasions requiring higher tensile strength, such as industrial machinery parts fastening. The material selection is based on practical use conditions, not excessive performance. The bolts go through standard processing to ensure the rod and head are firmly connected, without easy breakage during installation and use.

Product surface treatment

The surface treatment of these bolts focuses on rust prevention and smoothness, with no extra decorative processes. The most common treatment is electro-galvanizing, which forms a thin zinc layer on the surface. It’s low-cost and suitable for indoor dry environments, such as fixing household appliances or decorative parts. Some bolts get hot-dip galvanizing, a thicker zinc layer that offers better corrosion resistance for outdoor or humid scenarios like outdoor shelves or water pump components. Black oxide treatment is also used, giving a dark surface and basic rust protection, often applied to bolts for mechanical internal parts. The treatment process ensures uniform coverage, no peeling or spots. It aims to extend service life and avoid thread jamming during installation, meeting basic use requirements of most scenarios.
