Brass vs Bronze Screws

Posted by Fastenere on

Brass Properties: Higher malleability than zinc or copper. Low melting point (900 c); flows when melted. Combinations of iron, aluminum, silicon & manganese make brass corrosion resistant. Susceptible to stress cracking when exposed to ammonia. Not as hard as steel. CompositionBrass is any alloy of copper and zinc. Decorative; Low-friction applications (locks, gears, doorknobs, ammunition, valves); Plumbing/electronics; Musical instruments for acoustic properties; Zippers & uses where it's important to negate spark(fittings & tools around explosive gas).Used in boat and ship fittings, propellers and submerged bearings because of resistance to salt water corrosion. Widely used for cast bronze sculpture; Bearings, clips,...

What are Nylon lock nuts?

Posted by Fastenere on

A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut. It is a nut with a nylon collar insert that resists turning. The plastic insert is placed at the end of the nut, and its inner diameter (ID) is slightly smaller than the major diameter of the screw. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut by friction against the screw under the applied radial compressive force. Nyloc nuts retain their...

What are Tek Screws?

Posted by Fastenere on

Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole. The length of the drill point determines the material thickness which the screw can reliably penetrate.  When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined. These sheet metal screws are highly versatile and are used to attached metal, wood, fiberglass and plastic. The sharp threads draw material together and ensure a secure hold.
