Anchor bolts and foundation bolts are used to fix steel structures, equipment bases, machinery frames and construction components. Their material, thread, bend shape and finish should match installation conditions and project requirements. Clear specifications help reduce installation problems and improve quotation accuracy.
- Common shapes include L-bolts, J-bolts, straight anchor bolts, threaded rods and custom bent foundation bolts.
- Carbon steel is widely used for anchor bolts because it offers practical strength and process flexibility.
- Material grade should be confirmed when the project has structural or engineering requirements.
- Thread length, total length, bend length and hook shape should be clearly shown on the drawing.
- Hot dip galvanizing may be selected for outdoor or concrete-related corrosion protection.
- Zinc plating may be suitable for lighter-duty or indoor applications where appearance is important.
- Large anchor bolts may require special packing, bundling and labeling for project site handling.
- Buyers should provide drawings, standards, quantity, finish, destination and application before quotation.
