Thick steel plates are fixed with timber by bolts

Pay Attention To

Environment! INTERIOR or EXTERIOR?

Is the screw DRILLING CAPACITY suitable for your need?

When fixing THICK STEEL to timber, steel must be PRE-DRILLED.

Is the screw LENGTH enough for your fixture?

Screws pointside PENETRATION LENGTH should be at least 6x DIAMETER, unless it is not specified otherwise by the manufacturer.

Load-carrying screws should meet the requirements of the CERTIFICATES or STANDARDS

Is the COLOR important?

Important load-bearing connections with heavy loads should be calculated by CONSTRUCTION ENGINEER
