various types fasteners

Fasteners are made from a broad range of materials, ranging from common steel to plastic, titanium, or other exotic materials. Several materials are further subcategorized in order to differentiate between different grades which can help to describe specific hardening processes, alloy mixtures, etc. In addition to this, some materials are offered in a wide selection of platings or coatings which are used to improve its corrosion resistance or used to change the appearance of the fastener itself. Fastener material, grade, and coating may be critical when selecting a fastener due to variations between materials in strength, corrosion resistance, brittleness, galvanic corrosion properties, and cost.

Generally speaking, whenever replacing old fasteners, it is encouraged to best match whatever fastener you are replacing. It is not always safe to replace a bolt with a stronger bolt, as harder bolts are often more brittle, causing it to potentially fail in specific applications. Some equipment is specifically designed for bolts to fail before critical or more expensive items are damaged.

“Steels alloyed with molybdenum, nickel, and chromium (AISI 4037, 4130, 8630) are best if strength is required. These steels also have good cold-forming properties when annealed and can be heat-treated for the best combination of strength, toughness, and shock resistance,”

suggests David Zimmermann from Machine Design. Regular steel fasteners are more magnetic than most stainless steel fasteners, though some grades of stainless steel fasteners may be slightly magnetic.

“Fine-grain, fully killed (i.e., completely deoxidized) basic steel with no alloying agent. Low-carbon steels have from 0.06 to 0.22% carbon content (AISI 1008, 1010, 1018, and 1022) and exhibit good ductility for cold-forming. Medium-carbon steels contain 0.30 to 0.50% carbon content (AISI 1038, 1045) and are stronger but less ductile,”

Zimmermann added.

“These steels respond well to quench and temper. High-carbon steels contain 0.50% or more carbon (AISI 1066, 1095). They are difficult to cold-form unless annealed. They do, however, have high strength and can be heat-treated.”

When determining what grade a bolt is, it is best to reference the head of the bolt where it is typically marked for its grade. Many bolts are also marked with a manufacturer’s mark in addition to the grade marking.

Asian fastener market

New studies forecast the Asian industrial fastener industry to be worth over 44.12 Billion dollars as of the year 2020. Predictions based on a trend started in 2013, the Grand View Research Inc company have researched and expect the demand to increase over the next five years increasing total revenue. Offered in different sizes and dimensions these hexagon fasteners have endless amount of uses to connect and hold. As production of automotive, infrastructure, and the aerospace production increase the fastener industry does alongside with it.

As Asian countries such as China, India, Malaysia, Vietnam, Malaysia and Thailand plan to invest into innovation of their infrastructures over these next five years, it would be inevitable for them build without industrial fasteners such as bolts, screws, and rivets.Not only will infrastructures increase demand of fasteners, but will increase the need for a vehicle which will trickle down for more automotive rotable production in China. Production of different types of fasteners are required for the composition of rotables and in different parts of a vehicle.

“Increasing use of fasteners in the manufacturing of automotive parts including engine, body, molding, suspension system, frame, body assembling and wheels is expected to drive market growth.”

China's plans for innovation do not stop at infrastructures but branch off into the world of air crafts and aerospace, helping and boosting the demand for fasteners as well.  With approval of “The 2011 State Council Policy “it gives locals a chance to compete in huge industries.

“a growing number of provincial and local governments have announced new indigenous innovation policies that favor domestic products in government procurement processes, contradicting State Council rules.”

With regional manufactures on the rise since the policy, Chinese cities such as Shanghai, Chengdu, Xi’an, Jiangxi and Shenyang will contribute to the mass production of industrial fasteners over the predicted time of expansion of the industry.

Industrial Fasteners

Fasteners are commonly defined as devices that are used to mechanically join two or more components, devices or surfaces together. Objects that fall under the fastener umbrella are nuts, pins, rivets, clips, washers, nails, screws and bolts with the basic requirement for fasteners being that they must be sturdy/strong enough to handle the required loads and pressure. They must also be cost effective, resistive to corrosion, aesthetically presentable and easy to use.

The global market for industrial fasteners is gaining traction across the country with demand steadily on the rise consequently in part to the rise in construction and maintenance project increase. The demand for automobiles especially in emerging economies around the globe such as China, India and Brazil has also played a significant factor towards the overall growth of the global industrial fasteners market.

Research shows that upon further dissection of the global industrial fasteners market paints a picture with heavy emphasis on crucial market dynamics such as growth opportunities, major challenges and key drivers. A complete research report predicting the movement of the market can be found at This research report assess the statistical data of the existing players as well as new entrants into the global industrial fasteners market and determines how robust the industry actually is.

In fact the global market for industrial fasteners has been around longer than you think.

Zinc head screws

Triangle Fastener Corporation- one of the top fastener manufacturers, has recently released a new line of anti-rust Zinc head screws. Their zinc composition delay corrosion that would otherwise generate faster from screws made out of steel. Triangle Fastener has engineered all their products to outperform competitors in the industry.

To ensure this, TFC inspects each product every step of the way as a form of quality control. This new line of zing cap screws went through the same process. Every part of the screw is designed with a purpose. This includes the ZAMAX-5 Zinc Alloy Head that provides enduring strength. The shank composed of carbon steel is treated with Tri-Seal 1,000 hrs salt spray. The sealant improves the corrosion resistance of the screws by up to 20x more in comparison to zinc plated screws that typically hold a shorter lifespan.

The screw also comes with a EPDM sealing washer. It is an integral part of the screw due to the degree of corrosion protection that it provides.

ZAZ Bearings has released an article on June 6th 2016 talks about how ZWZ is working on creating six different bearings from their crystalline silicon slicing machine. These bearings will be used as import substitutes for one of their domestic customer. This has been delivered and put into good use.There has been more news stating that this specific customer has also placed another order with ZWZ for more multi standard bearings. With this being said, ZWZ is in production for these parts now.

It was this past May in 2015, a Jiangsu based company signed an agreement with ZWZ for the size different bearings for the crystalline silicon slicing machine spindle. The Jiangsu based company is also known as a technology company. The Jiangsu based company also deals with making polysilicon ingots as well as multicrystalline wafers that include crystalline silicon slicing machines. This machine is considered a key role in the production equipment that can possibly be used to import bearings.

There has been a recent spike in high demand for polysilicon products which could be due to how lucrative the photovoltaic industry has become. The country that is taking charge of the solar industrialization dealing specifically with high efficiency and low cost crystalline silicon is China.

ZWZ Bearings was established in 1938 in Wafangdian, Dalian in China. The company designed and manufactured its very first industrial bearing in 1949. The company went on to make their first automotive bearing in 1954. In 2013, the company expanded into different regions of China, specifically building factories in Liaoyang and Changshu.
