The Grace USA H2 Hollow-Ground Screwdriver Bit is precision-ground by Grace USA to a parallel-sided tip 0.200-inch wide and 0.033-inch thick, sized to seat squarely in a matching factory screw slot instead of tapering to a point like a standard screwdriver. That hollow-ground profile fills the slot’s full width and depth, spreading torque evenly across the slot walls and helping prevent the camming-out that chews up screw heads and surrounding metal. At 6.25-inch overall length, the H2 size covers screws in that particular width and thickness range. It’s built to be matched to the right size for each screw rather than forcing one universal driver to fit everything.

Key Specifications

• 0.200-inch tip width matches the screw slot it’s ground for.
• 0.033-inch tip thickness fills the slot’s depth to help prevent camming out.
• 6.25-inch overall length gives leverage and reach for the H2 size.

Frequently Asked Questions

What does hollow-ground mean? The tip’s sides are ground parallel instead of tapering to a point, so it fills a factory screw slot’s full width and depth instead of camming out.

How do I know which size I need? Match the tip width and thickness to the screw slot on the firearm; an undersized or tapered driver risks chewing up the slot.
