Spanner Screw Truss Round Tamper Resistant Drilled Drive Green Coat
The spanner screw drive uses two round holes opposite each other and is designed to prevent tampering. Other informal names include pig nose, drilled head or twin hole. This type is often seen in elevators and restrooms in the United States, the London Underground in the United Kingdom, some train wagons and the Montreal Metro in Montreal, Quebec, and is seen in all Panama Metro wagons. Ever Hardware provides the custom-made spanner screw and customizable packaging.
Truss head refers to a screw head that is extra wide and has a slightly rounded surface, or top. In other words, the head or top on the screw protrudes just above the surface to be fastened but contains a wider surface area just under the head.
These screws can be used for applications like securing thin membranes, such as one-ply, through insulation. Wooden truss head screws are also commonly used to attach cabinets to steel studs; or to attach sliding shelf supports, since the low-profile head of the truss head screw does not interfere with guide operation.
Truss head screws are well suited for sheet metal and other material with large diameter holes due to their wide head. Additionally, because of their low-dome shaped head, these screws make tampering with or removing the head difficult.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminum extrusions, drum hardware, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.
