Custom steel fasteners should be checked according to their function, not only their appearance. For U-bolts, bent bolts, threaded rods, anchor bolts and non-standard fasteners, inspection may involve material, dimensions, thread, bend shape, coating and packing. Clear inspection expectations reduce disputes and improve repeat order stability.
- Material should match the confirmed grade or buyer-approved equivalent.
- Key dimensions such as diameter, length, inside width, thread length and bend angle should be checked against the drawing.
- Thread quality should be reviewed for pitch, fit, length and visible defects.
- Bend shape and symmetry are important for U-bolts, J-bolts, L-bolts and right-angle bolts.
- Surface treatment should be checked for coverage, appearance, rust protection and handling damage.
- Packing should match weight, finish, quantity and export transport requirements.
- Photos or videos before shipment can help overseas buyers confirm product condition.
- Buyers should define critical dimensions and inspection standards when sending drawings.
