Next: 6 Lobe Pin TX Button Security Sleeve Anchor 
Prev: 5 Lobe Pin TX Button Self Tapping Security Screws 
- 5 Lobe Pin TX security screws offer higher security than the 6 Lobe equivalent
- Vandal resistant 2 way re-usable premium security screw with 5-lobe pin drive
- Tamper resistant and reusable security fixing
- Requires special insert bit to fasten and remove
- Usable for higher torque applications
The unique 5-lobe TX head requires a special driver bit for insertion making this an effective tamper proof fixing. The screws are very difficult to loosen without the tool.
This security screw is an upgrade from its predecessor (6-Lobe TX Security Screw) providing a higher degree of security as the design is less readily available.
Note: Special fasteners can be made to order with the 5-Lobe Pin drive subject to minimum order requirements.
Available from Fastenright in A2 Stainless Steel and A4-70 Stainless Steel (ideal for medical equipment security applications). Steel Zinc plated also available on request.
Sizes available from No. 6 to No. 14, with lengths ranging from 1/2″ to 3″. Please see the table below for further information.
