Coupler Mounting Kit M16 × 140 (BKC-2-16-140)

Secure heavy-capacity mono braked overrun couplers to deep trailer drawbar profiles with the Burquip Coupler Mounting Kit M16 × 140. Specifically engineered for heavy commercial freight trailers, equipment haulers, and tandem-axle caravans utilizing 3,000 kg mono braked overrun assemblies, this two-bolt Grade 8.8 high-tensile fastener pack delivers certified shear and clamping strength to handle high dynamic towing stress, sharp braking reaction forces, and severe shock loads.

Key Features & Benefits:

• Grade 8.8 High-Tensile Steel: Precision-manufactured to absorb continuous high-tonnage towing pull and abrupt deceleration forces without stretching, yield deformation, or shearing.

• Dedicated CBK3000BM Fitment: Specifically sized and rated for mounting the Burquip / KNOTT CBK3000BM (3,000 kg Mono Braked Coupler) directly to compatible drawbar assemblies.

• Extended 140 mm Shank Length: Designed specifically to pass cleanly through deep rectangular or square hollow section (RHS/SHS) drawbar beams and coupler mounting flanges, guaranteeing full thread engagement through the locking nut.

• Vibration-Proof Nyloc Retention: Includes matching high-strength nyloc locking nuts and heavy flat washers to prevent fastener back-off caused by corrugated dirt tracks and long-distance road vibration.

• Corrosion-Resistant Electroplated Finish: Coated in protective zinc electroplating to defend against rust, moisture, road grime, and salt spray exposure.
