Furniture pair locking cleat nuts

Main material: carbon steel

Main color: natural/black/white zinc plated/blue zinc plated/nickel plated, etc.

Main use: The locking nuts are widely used in the production, installation, repair, and maintenance of various mechanical equipment, electronic products, communication equipment, furniture equipment, medical equipment, sports equipment, the construction industry, and other industries!

Product categories: Beveled-edge head hexagonal slot cleat nuts with through hole, cross flower cleat nuts with through hole.Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. They're zinc plated to resist corrosion in wet environments. Barrel length is measured from under the head.

The 20 of 20 gauge steel refers to a carbon content of 0.2%, which is low carbon steel. The steel can be divided into low-carbon steel, medium-carbon steel, and high-carbon steel.

Carbon content: low carbon steel is generally less than 0.25%; medium carbon steel is generally between 0.25 to 0.60%; high carbon steel is generally greater than 0.60%.

In addition to steel contains carbon (C) elements and for deoxidation and contains a certain amount of silicon (Si) (generally not more than 0.40%), manganese (Mn) (generally not more than 0.80%, higher to 1.20%) alloying elements, does not contain other alloying elements (except for residual elements). Usually, the carbon content of less than 0.02% is called cooked iron, more than 2.11% to 4.3% is called pig iron, and the middle is steel.

The permissible stress of 20 gauge steel at 225℃: (16-36mm) 111-124MPa; (6-16mm) 117-131MPa

Permissible stress of 20 gauge steel at 100℃: 108MPa
