5-Lobe Pin security machine screws
Security Pin Torx Plus® screws provide enhanced security with the patented security Torx Plus (5 lobe with pin) drive & restriction of supply of the security Torx Plus drill bits.
5 Lobe pin fixings offer greater security than 6-lobe Pin torx fasteners, whilst maintaining the high-level torque capability.
Featuring a vandal resistant 5-Lobe TX Head that requires a special driver bit for installation, the unique drive renders these screws tamper-proof – reducing the risk of vandals or intruders tampering or undoing the screws.
Suitable for higher torque applications, this fastener is also a two-way reusable fixing making it ideal for continued installation and removal if maintenance is required.
Available from stock in A2 Stainless Steel 
and A4-70 Stainless Steel.
