North SONAR FUSELAGE SCREW PACK BM8x35 TH CS Screws with washers

Sonar Fuselage Screw Pack B attaches your Sonar A600 or A700 Fuselage to your Sonar AF or CF Mast.  ATTENTION:  Sonar Fuselage Screw Pack B (M8x35 TH CS T40) is designed to fit Sonar Fuselage and Carbon Fuselage with straight holes. Some earlier models of the Sonar ... Carbon Fuselage do not have countersunk holes, so will require this Screw Pack B (M8x35 TH CS). Newer models of the Sonar Carbon Fuselage will have tapered countersink holes. These allow the head of a flathead screw to sit flush with the top of the fuselage.  Tapered holes = Screw Pack B2. If your carbon fuselage has tapered holes (similar to your Sonar front wing) you will require the Sonar Fuselage Screw Pack B2 (M8x30 TH CSK T40 - 85009.240145). If you are wanting to attach an HM Carbon Mast to your Aluminium or earlier model carbon fuselage with straight holes, you will need Sonar Fuselage Screw Pack B3 (M8x25 TH CS).
