Burquip Coupler Mounting Kit M12 × 150 (BKC-2-12-150)

Ensure rigid, road-safe attachment of overrun brake assemblies and tow ball couplers to your trailer drawbar with the Burquip Coupler Mounting Kit M12 × 150. Engineered specifically for heavy-duty commercial trailers, caravans, and boat transporters, this high-tensile fastener kit provides the extended shank length required to bolt through deep square-hollow-section (SHS) and channel drawbars, delivering certified clamping strength capable of handling continuous dynamic towing loads.

Key Features & Benefits:

• High-Tensile Fastener Rating: Manufactured from Grade 8.8 high-tensile steel, providing exceptional shear and tensile strength to withstand extreme towing forces, sudden emergency braking, and shock loads.

• Extended 150 mm Shank Length: Designed specifically for deep-section drawbars, heavy-gauge box tubing, and spacer blocks where standard shorter bolts cannot achieve full thread engagement.

• Vibration-Resistant Locking: Supplied with matching high-strength nyloc locking nuts and heavy-gauge flat washers to prevent fastener loosening caused by rough gravel roads and high-frequency chassis vibration.

• Corrosion-Resistant Coating: Finished with a protective electro-galvanised / zinc plating that resists rust, road spray, salt, and harsh weather exposure.

• Precise Coupler Fitment: M12 bolt diameter matches standard overrun brake mounting flanges and unbraked ball coupler hole profiles without sloppy clearance or binding.
