Penta bolts, as the name suggests are constructed with pentagonal heads. This means the head of the fastener has five sides. According to most Penta Head Bolts Manufacturers In India, these fasteners tend to be resistant to tampering. And therefore, these fasteners in no way could be loosened by the use of typical hardware store tools. Generally, the most common hardware tool for multi-side fasteners is a spanner or wrenches for hex bolts.
The spanner or wrench to be used for these fasteners must correspond to the Penta Head Bolt Dimensions. The use of these fasteners is frequently associated with securing manhole covers. Since they are free from tampering, Penta head bolt manufacturer in India often recommend their use in applications that demand a high level of security. The diameter of these Penta Head Security Bolts ranges between ⅜ inch to 2 ¼ inches.
Just as the other fastener varieties are available with coatings or electroplating, it is possible to use such treatments on the surface of the Penta-head Cabinet Door Bolts. Coating or the use of some surface treatments on the Penta Head Lag Bolts improves some of its mechanical properties and its resistance to corrosion. For instance, a zinc coating on the Penta Head Bolt Socket improves its toughness, by making it hard, while also increasing its resistance to oxidation corrosion to a certain degree. Today, since there are various specialized treatments that are available for the fasteners, it is possible to ask Penta Head Bolts Suppliers for the use of specific treatment on the fasteners. In addition to materials like alloy steel or even carbon steel, it is not uncommon to see the Penta Head Bolts Stainless Steel available in the market.
