🔍 Key Concepts

• Carefully distinguish between taper angles on the working end and the chamfer on the knurled gripping portion • Remember that an included angle is the total angle from one face of a bevel to the opposite face, not just the angle from the centerline • On mechanical drawings, a single angle callout on one side of a symmetrical chamfer usually represents half of the included angle

💭 Think About

• On GS-0014, which specific edge is described as the chamfer on the knurled end, and what angle is marked closest to that edge? • If that chamfer is symmetric about the centerline, how does the labeled angle relate to the full included angle between both sides of the chamfer? • Looking at the choices, which one matches twice the indicated single‑side chamfer angle shown near the knurled portion?

✅ Before You Answer

• Verify which dimension arrow actually points to the knurled‑end chamfer, not the working taper on the opposite side • Confirm whether the angle shown is measured from the centerline or from the face of the part • Before choosing, mentally sketch or imagine both sides of the chamfer to visualize the full included angle between them
