Home / Screws & Bolts / Security Fasteners / Hex Pin Drive / Hex Pin Button Head Machine Screws Product Description M4 x 12mm Hex Pin Button Head Security Screws - A2 Stainless SteelHex Pin Button Head Security Screws, also known as Pin Hex, feature a domed head and an internal hexagon pin socket drive. The hexagon pin drive allows for force to be more evenly distributed whilst tightening. This means a higher level of torx can be applied to the fixture and also reduces the chances of cam-out, which may cause damage to the screw drive. The internal pin drive adds a level of security to these screws, as a standard hexagon socket bit cannot be inserted. These security screws must instead be paired with a security drill bit, resulting in a tamper-proof fastening. Click Here to view the installation video. These Hexagon Pin Button Head Security Screws are made from A2 Stainless Steel which provides corrosion and oxidation resistance.For larger quantities or items not listed, please email sales@gwr-fasteners.co.uk and one of our team will provide you with a quotation.
