We produce security fasteners in a wide range of sizes, from (M.8) up to (M.16) for Fencing Industry and for transmission towers. Each customer has a unique security bolt with nut and the matching torque requirement. We manufactured customised anti theft bolts and nuts specifically for them. We manufactured the security nut and have capability to make a unique security nut for each customer as well (call 0091-9988167802 for pricing). Standard tamper-resistant bolts and "specials" are also produced in our plant. Known as the high security bolts nuts specialists, we provide the best secure Anti theft Bolts and Nuts in the world.

Our method of making unique security screws is difficult but cost-effective. The security bolts and nuts are made using a process called cold forging. This means that our security shapes are forced into the head of the screw with up to 50 tons of pressure as rapidly as 100/minute. Special tamper-proof screw tooling is used, requiring highly experienced specialists & a great deal of time.

Though our high security bolts and nuts are a little more expensive than regular bolt nuts, the added security is worth the additional cost - especially when one considers that these security fasteners are locks, not just tamper-resistant Bolts & Nuts.

And if we don't have a fastener to fit your needs, we will custom design a bolt, nut & fittings to your specifications.
