NoGo™ Security Fastener Covers.

What are NoGo™ Security Fastener Covers?

Home Office approved and winner of the ‘Sold Secure’ silver award, NoGo™ is a 2-part enclosure from Hafren Security Fasteners. This patented anti-tampering security component doesn’t require specialist tools for installation and is designed to be used with any standard fixing.

NoGo Security Fastener Covers come in 2 different Enclosure types. NoGo Type 1 is designed to be used with bolts and screws, with the cap enclosing the head of the fastener, whilst the NoGo Type 2 features a cap with central hole, designed to fit over protruding threads. 

For both Enclosure types, once the standard fasteners inside have been installed to the desired torque, the NoGo Cap simply needs to be hammered into the base to create a permanent fixture which is near impossible to access.

Materials

NoGo Enclose Type 1 cover caps for bolts and screws are available from Accu in Case Hardened Zinc Plated Steel (Cr3).

NoGo Enclosure Type 2 cover caps for protruding threads are also available in Case Hardened Zinc Plated Steel (Cr3).

Sizes

Both Type 1 & Type 2 NoGo Security Fastener Enclosures are compatible with thread sizes M5, M6, M8, M10 and M12.
