How should you proceed to prevent cross threading when starting fasteners?

• A. Use a torque wrench only
• B. Start all fasteners by hand before tightening with tools
• C. Cross-thread intentionally
• D. skip pre-alignment

Answer: (B)

Starting fasteners by hand ensures the threads engage straight and true before any torque is applied. Hand-threading lets you feel for binding and guide the bolt or screw along the correct axis, catching misalignment early and preventing cross-threading that can gall, strip, or damage the hole or nut. Once the fastener turns smoothly by hand and threads are fully engaged, you then tighten to the specified torque with the wrench to achieve proper seating and clamping force. Relying on a torque wrench alone can’t fix a misaligned start, and skipping pre-alignment increases the risk of damaged threads and a weak joint. So begin by hand to ensure alignment, then complete tightening with the proper tool and torque.
