Wood screws Wood lag screws are commonly used in timber construction work, such as building frames, fixing joists or rafters, securing beams and assembling wooden parts. They can also be used in carpentry and joinery projects to assemble smaller pieces of wood. Wood screws are very robust and offer excellent resistance to heavy loads, making them ideal for projects requiring great strength and stability. A4 stainless steel A4 grade steels, alloyed with molybdenum, are "acid resistant" and provide better corrosion resistance. A4 is used extensively in the cellulose industry as this grade of steel is developed for boiling sulphuric acid. It is also suitable to some extent for chloride environments. A4 is also frequently used in the food and shipbuilding industries. ISO / DIN standards This product complies with DIN 571 - (NFE25-607, UNI 704) standards.
