Security Lock Nuts

TFH Security Lock Nuts are a specialised fastener designed to secure fence panel clamps to temporary fencing so they can only be removed using a custom lock nut tool. This significantly reduces the risk of unauthorised removal of fencing clamps and deters opportunistic site access by preventing standard tools from undoing the fittings.

Key Features

• Requires a custom lock nut tool for removal — not removable with standard tools
• Secures fence clamps to panel connections to prevent unauthorised disassembly
• Deters opportunistic site access and fence tampering
• Compatible with standard TFH temporary fence clamp fittings

Common Applications

• High-security construction sites where fence tampering is a risk
• Events requiring secured perimeters overnight
• Urban sites in high foot-traffic or high-risk areas
• Any installation where standard fencing security needs to be upgraded
