Pentagon head bolts resemble standard hex bolts in appearance, but their unique pentagonal head requires specialized industrial tools for installation and removal. This effectively prevents malicious tampering and vandalism in public areas, offering a significantly higher security level than common anti-theft screws. The products are specifically designed for harsh outdoor and underground environments such as municipal manhole covers, water meter boxes, and electrical enclosures, featuring exceptional long-term corrosion resistance.

As a professional fastener factory, we strictly follow your drawings or samples to provide OEM/ODM customization services in various metric and imperial specifications. With stringent tolerance control, we ensure every bolt perfectly matches the standard pentagon tools available on the market.
