5-Lobe Pin TX Countersunk security machine screws (TX24) offer a more secure version of the more common 6 lobe TX security screws, instead featuring a 5 lobe design reminiscent of a flower petal. This design combined with the security pin in the drive recess means that these screws are only removable using matching drive bits. The supply of these bits is restricted.

5-lobe Pin TX screws are also available as a button head here.

Available from M4 to M6 as standard in A2 stainless steel with other sizes and materials available to order.
