PVC (Polyvinyl Chloride) is a highly durable and versatile material that is used in a wide variety of applications. It has many great properties including, strength, durability and resistance to erosion and corrosion.
Hexagon Bolts
Hex bolts (also called hex head screws) have six-sided heads that create greater torque, or turning force, than square or round headed bolts. They can be installed or removed with socket wrenches without the need for a nut, and they are commonly used to fasten infrastructure that requires high-tensile strength. They have more surfaces that a wrench can grip, making them easier to use in tight spaces. Hex bolts are available in a variety of sizes, materials, specifications, and finishes.
Hex bolts are made of steel or stainless steel and may be fully threaded or partially threaded. They are available in black oxide, blue phosphate, zinc yellow, and other finishes for different environments and application requirements. Hex bolts in black oxide have a dark finish that resists corrosion in dry environments. Zinc yellow bolts are corrosion resistant in wet environments, while NL-19 finishes have corrosion resistance comparable to black oxide. They can also be coated with a coating to increase corrosion resistance, improve appearance, or facilitate threading in difficult-to-reach areas. Hex bolts that meet military specifications are ideal for demanding applications and extreme conditions.
Hex Head Bolts
Hex head bolts are a commonly used fastener type found in a variety of environments and scenarios. The hex head design distributes torque across multiple sides for high strength and reliable security. They are M16 large head PVC typically installed into pre-tapped holes or with nuts and can be tightened using hex bolt wrenches, socket sets, hex keys and ratchet spanners.
Hex bolts come in a variety of sizes, materials and specifications but they all share one thing: a hexagonal head. Unlike square heads, which have only four sides, hex bolts have six and provide more surfaces to grip with standard wrenches and socket tools. This allows for the creation of more torque, or turning force, making it easier to loosen or tighten hex head bolts.
Grades for hex head bolts range from grade 5 to grade L9. The higher the grade, the stronger the bolt. Grade L9 bolts are made of highly alloyed steel and are fully heat treated versus case hardened for high stress applications like tractor fabrication, suspension and other heavy demand jobs.
Combi screws, which combine two different head types, are also available for use with hex head bolts. They can include hex and Phillips head combinations for use with a screwdriver and are ideal for landscaping, lumber and thick sheet metal applications that require more torque than standard hex bolts.
Threaded Bolts
Bolts are available in a wide variety of styles and materials. They can be made from titanium, which is extremely strong and light or steel, which is durable and corrosion resistant. These bolts can also be finished with different coatings, which can enhance the appearance and durability of a fastener. For example, black oxide is a processed form of rust that is durable and non-corrosive, while chrome is highly reflective and attractive. Bolts are also often coated with zinc, which acts as a sacrificial anode and protects the underlying metal from corrosion.
A bolt’s thread size can be specified in a number of ways. The most common is to use a threads per inch (TPI) count, which indicates whether the threads are fine or coarse. Most hardware produced in North America is measured according to this standard. A coarse series thread is less expensive than a fine series, and it may be more readily available from stockists.
The tensile strength of a bolt is the amount of pressure it can withstand before it breaks. This is important to know when choosing a fastener for an application because it is used under tension, which can cause it to stretch and lose its elasticity. It is also helpful to understand how much a fastener can withstand in order to design an assembly that will not be too stressed.
Zinc Plated Bolts
Steel fasteners are made in a variety of materials, but many common types are plated for extra durability. These plated fasteners are more resistant to corrosion caused by chemicals, water and sunlight than non-plated options. Stainless steel is an especially durable option that resists rust and corrosion, but it has a higher upfront cost than other materials.
Stainless steel screws are a versatile choice for a wide range of applications, from joining metal pieces together to securing objects in harsh environments. They are available in a number of finishes, including black oxide, zinc yellow and hot-dipped galvanized, to protect them from the elements.
Grade 5 hex cap screws are a heavy-duty option that is heat-treated to create an extremely hard fastener. They have waterproof connector manufacturer a high tensile strength and meet ASME B18.2.1 dimensional standards and SAE J429 material quality standards. Black oxide screws are a great choice for dry environments while zinc yellow and hot-dipped galvanized options work well in wet areas.
Hex bolts have a six-sided head and are either fully or partially threaded, making them ideal for gripping and anchoring thin surfaces. Carriage bolts are shaped with a domed head and can only be removed from the nut side, giving them extra security for hinges and locks.
