North SONAR CARBON FUSELAGE SCREW PACK B2M8x30 TH CSK

Titanium countersunk screws to attach your Sonar Carbon Fuselage to your Sonar Mast. The Sonar Carbon Fuselage Screw Pack B2 (M8x30 TH CSK T40) is designed to fit Sonar Carbon Fuselage with tapered countersink holes. How to identify the correct screws for your ... carbon fuselage: More recent 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). Straight holes = Screw Pack B. Some earlier models of the Sonar Carbon Fuselage, and all aluminium models of the Sonar Fuselage do not have countersink holes, so will require Sonar Fuselage Pack B (M8x35 THCS T40 with M8 Washer - 85009.200136). Note: If you have an earlier Carbon or an aluminium Fuselage, and you wish to use it with an HM Mast, you will need to swap to the 25mm B3 Screw Pack supplied with the HM Masts.
