Step 7Oval Head Security Screw

Oval Head Security Screw
[[br]]
Oval Pan Head Security Screws are unique in the sense they have no conventional drive slot in the head. The screws must therefore be installed or removed using a special recessed driver that precisely accommodates the oval head. This unique feature renders the Oval Pan Head Security Screw vandal-resistant, reducing the risk of vandals or intruders tampering or undoing the screws. The head gives a deceptive appearance, looking like a stud or rivet. Due to the design of the Oval Pan Head Security Screw it is suitable for low to medium torque applications and is "2 way".

The special hand driver is available in two sizes - OP4 for M4 screws and OP56 for M5 and M6 screws
