So, I thought I would have a play with recently acquired HW35 whilst watching a film. Checked the power, it is a bit close but there is deiseling so a strip and de-lube is required. No biggy, had planned to strip it anyway.

Off come the sights, no issues. Out come the stocks screws, no issue. Lift off stock and a grub screw makes a bid for freedom! Where the heck did that come from?? Turns out it is the screw that adjusts the Sears that sticks out of the front of the trigger assembly. No problem thinks I, but hold on it is a torx head. I hunted through my tools, I have torx keys that are too small, I have torx screws that are too big but nothing of the correct size, nor any other tools that will fit at a push. Flippin' typical

Anyone know offhand what size I need to hunt down tomorrow.
Cheers
