How should field bevels be prepared for bolt seating?

• A. Field bevels should be cut to the required bevel size, with burrs removed to ensure proper bolt seating and alignment.
• B. Field bevels should be left as-is with burrs
• C. Bevels should be ground smooth but rounded edges
• D. Field bevels should be oversized to allow play

Answer: (A)

Proper bevel preparation ensures the joint can close fully and the bolt seats correctly. Bevels must be cut to the required bevel size so that the bearing surfaces meet flush and there’s no binding when the bolt is tightened. Removing burrs is essential because burrs create sharp edges that can foul the bolt head or nut, trap dirt, and prevent smooth seating or accurate alignment. A smooth, correctly sized bevel allows the pieces to align properly and the bolt to seat securely, reducing the risk of gaps, misalignment, or damage to threads. Bevels should not be left oversized or with burrs, and they should match the specified angle and depth.
