Extra Secure 5 Lobe Pin Button Head Security Machine Bolts A4
This 5 lobe security bolt is by far our most secure standard two-security fixing. This is because - unlike the 6 lobe pin torx screws and pin hex screws - the driver inserts for attaching and removing these bolts are not readily available from standard DIY outlets.
The other benefits of these bolts is that they can be used anywhere – on land or sea. Being manufactured A4 stainless steel these can be used almost anywhere, including marine applications, within food processing and distribution, on or around medical equipment and in coastal towns and villages.
Finally, these impressive bolts have achieved our maximum torque rating. In essence this means these screws can be tightened up as far as you need without the driver insert easily breaking or the screw head becoming damaged.
Delivery: if ordered before 3:30pm, Monday-Friday, these screws will be dispatched on the same working day
Please note, when ordering these screws for the first time, you will also have to order the corresponding driver insert shown below.
Finally, please note the length measurement does not include the bolt's head. It just relates to the threaded section below the screw head.
