A variation of Accu’s standard Socket Button Head Screw, this alternative incorporates an integrated flange, eliminating the need for a separate washer.
As with the standard Socket Button Screw, this fastener features a low-profile rounded head, free from sharp or pointed edges, making it ideal for both safety and aesthetic reasons.
Fitted with the widely available Allen (Socket) drive, Socket Flanged Button Screws are a popular choice for decorative applications and can be installed using the appropriate sized Accu Hex Key, or with a Hexagon Driver Bit.
Socket Flanged Button Screws are available from Accu in A2 and A4 Grade Stainless Steel, in natural finish, with pre-applied Thread Locking Patches or a Chemically Blackened finish. High Tensile Steel (10.9) variants are also available as standard, in either natural or Zinc Plated finish, depending on the size of screw required.
