Penta bolts are made with pentagonal heads, as their name suggests. This indicates that the fastener's head has five sides. The majority of Penta Head Bolts Manufacturers in India claim that these fasteners often have a high level of tamper resistance. As a result, using standard hardware store tools to release these fasteners was impossible. A spanner or hex wrench is typically the most popular hardware tool for multi-side fasteners.
The penta head bolt dimensions must match the spanner or wrench that is to be used for these fasteners. These fasteners are widely used to hold manhole covers in place. Penta head bolt manufacturers in India frequently advise using them in applications that demand a high level of security because they are impervious to manipulation. These Penta Head Security Bolts have a diameter that runs from 38 to 2 14 inches.
Penta-head Cabinet Door Bolts can have their surfaces treated with coatings or electroplating, much like other fastener types are available. The Penta Head Lag Bolts' mechanical characteristics and corrosion resistance are enhanced by coating or other surface treatments. For instance, a zinc coating increases the toughness of the Penta Head Bolt Socket by making it hard and, to a certain extent, boosting its resistance to oxidation corrosion. Today, you can ask Penta Head Bolts Suppliers to employ a specific treatment on the fasteners due to the availability of a variety of specialist treatments for 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.
