20mm Stainless Metal Washers For Windsurfing Fin bolts
Starboard K9 Anti Twist Plate
M8 Torx Head Counter Sunk Screw 20mm – 50mm
These are stainless steel M8 (8mm thread) counter sunk screws.
We do try to stock all M8 screws with the more widely used T40 Torx heads but it has proved difficult so unfortunately we have a mixture. You can use a T40 tool in T45 screw head but it is not ideal and will eventually round out the head. From the brands that we sell the main sizes are T30 and T40.
Screw sizes and Torx tool head size:
- 20mm = T45
- 25mm = T40
- 30mm = T40
- 35mm = T45
- 40mm = T40
- 50mm = T40
