RAM® Tボルト 1/4"-20 x 7/8" ロング

This T-bolt is the exact right length for my mount setup, and the 1/4"-20 threading matched perfectly with my existing hardware. Feels solid and well-machined, no wobble once tightened down.

Swapping a worn bolt on my track-ball mount was quick once I had this exact 7/8" length replacement in hand. The threads caught perfectly and it tightened down just as firm as the original.

Finally got a spare for my track-ball mount and it fits perfectly into the existing hole without any wobble. The 1/4"-20 threading matches exactly what came with it, so replacing the lost one took under a minute.
