Hexagon socket bolts, socket head adjusting screws

Hexagon socket bolts are the ideal solution for situations inaccessible to a flare nut spanner. We have also included socket head adjusting screws in this product group; these components are notably used for the positioning of construction elements.

Hexagon socket bolts are primarily used in the automotive industry and for engines in the offshore industry and ships.

Tailor-made and supplementary services from Triofast

If required, we can drill securing holes in your bolts and adjusting screws. This includes the possibility of drilling a hole for a split pin at the bolt extremity, or a securing hole in the head or a narrowing in the centre. If you supply the blueprint, we will arrange it for you. So far, we have responded successfully to all the challenges we have had to face in this area. Just one example: M48 bolt, length 640mm – split pin hole drilled in the extremity and at a central narrowing of the shaft. You just shout, we’ll take care of it!
