Mild steel is a type of carbon steel. There are different grades of mild steel, with it containing anywhere between 0.05 to 0.25% carbon. Additives give it critical properties such as corrosion resistance, tensile strength and wear resistance. Push-in blind rivets are so called because they can be installed even if you can’t access the rear side (“blind” side). An example is a clinch rivet. All you need to install it is a pop rivet installation tool. Another type of blind rivet is the drive rivet. The drive rivet has a short mandrel that protrudes from the head. It’s placed into the hole and a hammer is used to drive the mandrel in, flaring out inside the hole to provide a secure, load-spreading fix. Drive rivets have a specific application, used to secure panels and architectural features to masonry walls. Polysulfone (PSU) is a transparent material with high-impact resistance. It provides high performance, has good electrical properties and resistance to chemicals. One reason for its popularity is its outstanding hydrolytic stability against hot water and steam sterilisation. It performs especially well in high-temperature environments and resists detergents and hydrocarbon oils even in those conditions, under moderate stress levels. US-based woodmaker and youtuber andrew klein has revealed his ‘next big thing’: a screw with invisible slots that disappear completely. instead of needing to be hidden like ordinary screws, this precision-crafted innovation can be integrated into any design as a decorative accent, as the holes are only visible when the screwdriver is introduced, completely disappearing once the tool is removed. created with the purpose of aesthetics in mind, these new screws are ideal for carpenters who want an extremely clean and seamless look on their finished pieces. What’s the difference between a threaded rod and threaded stud? That depends on who you talk to. In some quarters, they’re one and the same. To others, a threaded stud refers to a shorter length than a threaded rod. A stud also often has a slot in the end for installation.

Polyoxymethylene (POM) is also known as acetal. It’s a highly crystalline thermoplastic favoured for its stiffness, hardness, and low creep under stress. It also provides high flexural and tensile strength, has a low coefficient of friction, excellent chemical resistance and outstanding fatigue properties. The flip side is, POM has moderate heat stability and insufficient flame resistance. While it’s the perfect material for many applications, it’s not ideal for those where heat is involved. The shoulder washer is also referred to as an insulation sleeve because it insulates rivets, screws or wires. A nylon shoulder washer, for instance, can be used for connections between incompatible metals. Another nylon shoulder washer is designed to reduce vibrations. A plastic shoulder washer can also be inserted into a housing, giving a rotary application a bearing surface. Another of its capabilities is that it stops heat from flowing through the screw to other parts of the assembly. You can learn more about washers in our guides: When to use plastic washersand How and when to use washers effectively. You’ll find that nylon 6.6, a variant, is stronger still, and absorbs less moisture than standard nylon. When a high level of torque is required in your fastener, it’s the ideal material. Nylon 6.6 is popular and used to make everything from fasteners to cable ties.

To figure this, you’ll need to convert .183 to 1/32s. To do that, start by taking .183 and divide by 1/32. Here’s the formula: PEEK (polyetheretherketone) is a high-performance plastic that maintains stiffness at high temperatures. It has outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. Another benefit is its resistance to steam and water. All of these reasons make it a favourite of the healthcare industry. Washers are used to distribute the load of threaded fasteners by increasing the surface area. They reduce the risk of stress-related damage to the material that the threaded fastener is driving into. Sometimes, washers can give you spacing as well, preventing your fastener from going deeper into the material than you might want.

Polycarbonate is tough and transparent. It provides high impact strength and high modulus of elasticity. Other benefits include its high heat deflection temperature and very low moisture absorption. It’s a popular material for electrical and electronic applications due to its low frequency and high-voltage insulating properties. Because of its strength and transparency, it’s also ideal for point of sale and displays. You might find it helpful to read our guide: When to use polycarbonate fasteners. The material has good impact strength, pliability, and is cost-effective. It also offers excellent electrical resistance, so it’s often used in electronics. You’ll find polypropylene used in pharmaceuticals, too, due to its high resistance to many chemicals. For example, an acetal dowel pin is inserted into receiving holes, which hold parts of an assembly together through the use of friction. A tight fit keeps the parts firmly together in fixed alignment. Nuts, which have threaded holes, work in conjunction with bolts, strengthening the parts they hold together. Usually, most nuts have a hexagonal shape. This is only on the exterior, while the interior is actually cylindrical. The purpose of the hex exterior is to make installation easier. Six sides makes the hex nut easier to grip, which translates to easy installation or removal.Rivet lengths typically come in 1/16 inch increments. Just as we did with the diameter, we have to convert our .39425 figure by dividing it by 1/16. Our formula now looks like this:

Push-in rivets, also called push rivets, are particularly popular, as they come in so many different styles. Most simply push into place by hand, hence the name. In some cases, you’ll need a push rivet installation tool, which is easy to use. You can also get removable plastic rivets, which allow you to access the panel and then reuse them.

Snap rivetshave male and female parts that pass through the panels to join together and present a finished edge on both sides. Snap rivets are a type of push-in rivet.
