RUKO SPB-DIN1869-8,5mm-Serie-2 T-Head Bolt M8 x 25 mm Steel 8.8 Plain

This RUKO T-head bolt is engineered for secure clamping in machine tools, jigs, and fixtures where a standard hex head would obstruct the workpiece or tool path. The T-head design slides directly into a 10 mm T-slot, providing a low-profile, anti-rotation anchor point for fast, repeatable setups.

Highlights

• DIN 1869 standard T-head bolt for T-slot clamping systems
• M8 coarse thread with 25 mm under-head length
• Steel strength class 8.8, plain finish
• Head width 18 mm, head height 6 mm
• Suited for jigs, fixtures, and machine tool workholding

In daily use

Slide the T-head into the slot, align your clamp or strap, and tighten from above with a nut or threaded accessory. The plain steel surface offers a firm grip and can be protected with oil or coating if corrosion resistance is required. The 8.8 class provides high tensile and yield strength for demanding clamping tasks.
