M8 SOCKET (5mm) CSK A4 ST/ST MACHINE SCREW - WINDFOILING, WINGFOILING, SURFOILING & KITESURFING FOILS TYPICALLY USED FOR WINGS-FUSELAGE-MAST & PLATE HEAD to BOARD.

M8 SOCKET (5mm) CSK A4 ST/ST MACHINE SCREW - WINDFOILING, WINGFOILING & KITESURFING FOILS.

Top quality A4/316 Stainless Steel Screws to fit most popular foils produced for Wind, Wing, Surf and Kite Foiling boards and foils.

Typically used for securing plate heads to most solid boards in 30 to 35mm lengths (check your requirement's before ordering - Fanatic foils for instance usually need 30mm with a stepped T nut, but some boards will allow 35mm with either stepped or a flat nut)

We also have these available in all the popular sizes we have so far found being used for Wing to Fuselage and Mast to Fuselage attachments where these are M8 threads with CSK Heads (most companies use M8 or M6 - we try to stock them all)


Be sure that your thread is M8!

If you are unsure and cannot measure the screw needed accurately, always insert the screw at least 4 complete turns very gently by hand - if this is easy, you can be pretty sure you have the correct choice and will not cross the thread and risk stripping it.

The standard sizes we stock of M8 SOCKET (5mm) CSK A4 ST/ST MACHINE SCREW are 20, 22, 25, 30, 35, 40, 45 and 50mm long.

Please Remember - Countersunk screws are measured 'total length' including head.

For Button or Pan head Screws, the length is the Thread below the Head.

Other sizes and custom lengths can often be supplied - please e mail for advice?
