M12 x 120mm Torx Button Head Screws (ISO 7380) - A4 Stainless Steel Torx Socket Button Head Screws, also known as Dome Head Screws, feature an internal Torx Socket Drive which, allows for a more even distribution of force whilst tightening and reduces the chances of cam-out which may cause damage to the screw drive. The Torx drive also allows for a higher torque to be applied to the screw resulting in a more secure fixture. These are often used in jobs that require minimal head protrusion. These Torx Socket Button Head Screws are made from A4 Marine Grade Stainless Steel which provides corrosion and oxidation resistance as well as increased resistance in harsh chemical and outdoor environments.
