Plastic bolts, metal nuts . . . Should have been quick, easy assembly. No. No. Bolts resisted, indicating risk of stripping threads. Slowly, carefully meld bolts and nuts before attempting assembly. Difficult. Exacting. Now, separate bolts and nuts. Should meld smoothly with second attempt. No. No. Even more challenging when assembling because of restricted view. 45 minutes of agita for what should have been a 10-minute job of joy.
