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.

Bolts are often confused with screws, because they do similar jobs. Bolts join two unthreaded components, while screws join threaded components. Usually, the head of bolts is bigger than the shaft. While screws are most often tapered, bolts are not. A bolt needs a nut for tightening, while a screw works on its own. In the example shown here for one specific size, this is what you’d see among the relevant product information. You don’t have to calculate anything. If your parameters fit what you see in the table, then that’s the rivet size you want. 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. Acetal provides high strength and stiffness. Its good dimensional stability makes it an easy material to machine. A semi-crystalline material, acetal has good chemical resistance. It offers a low coefficient of friction and good wear. It has very low moisture absorption while resisting abrasions.

With good resistance to oils and low permeability to gases, PVC is inherently self-extinguishing. This makes it an excellent material for wire and cable insulation.

Rivets serve as another type of panel fastener, although their purpose is broader, joining together other items as well. 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. Need:Easy installation in restricted space for general fixing purposes or attaching components to panels

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. klein shares that this new project was inspired by wire cut EDM demonstration toys that show two pieces of metal sliding against each other and coming together so perfectly that the seam disappears. the designer took this popular, ‘satisfying’ concept and made it into something functional: a new screw that looks like a smooth disc, with no (visible) slots, as well as a screwdriver to complete the set. the newly introduced system uses stainless steel magnets, so that the driver is held in the screw without the little plunger pushing it out.Cover Caps and bases can be mixed and matched in six different colours to create a customised appearance Panel fasteners do what the name says: they connect items to panels. They do this on the edge or through holes or slots. However, not all panel fasteners go by that name. Snap rivets are a prime example. Another solution are quarter-turn panel fasteners. These are typically used to secure a panel or cover, yet still enable easy access. Comprising of two pieces, quarter-turn fasteners join a fixed surface with a removable one. The base fits into the fixed panel, and then the slotted screw is inserted through the panel that can be removed, and into the fastener base. A quarter turn of the screw secures – or loosens – the panels. For more solutions that can fasten panels, go to rivets. You can also learn more in our Guide to panel fasteners. Polypropylene can also stand up to UV exposure, and depending on the environment, it can be a good choice for outdoor use, especially when you consider that it doesn’t absorb or emit moisture. However, it’s not suited for freezing temperatures, as it can become brittle. 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: We’ve designed this guide to help you understand your fastener and fixing types, materials, and applications from screws and washers to nuts, rivets and everything in between.
