Which assembly jig is designed specifically for piloting and driving screws into two work pieces oriented at 90 degrees, enabling pocket-hole joints?

• A. Pocket Hole Jig
• B. Drill Vise
• C. Strap Clamp
• D. Pipe Clamp

Answer: (B)

The essential idea is that pocket-hole joints require a tool that guides the drill at a precise angle to create holes in one piece so a screw can pull two pieces together at a 90-degree orientation. A pocket hole jig is built specifically for this: it provides the fixed angle, positions the drill bit, and often includes clamps to hold the pieces steady while you drive the screw. This combination lets you pilot the hole accurately and drive the screw so the two pieces meet at 90 degrees with a clean joint.

A drill vise, by contrast, is for holding a drill or workpiece still during drilling, but it doesn’t supply the angled pocket-hole guidance or the joint setup needed for 90-degree joining. Clamps like a strap clamp or pipe clamp are meant to hold pieces together during fastening; they help with pressure and alignment, but they don’t create the pocket holes or guide the drilling process itself.
