U-bolt clamp OEM M8 50x140 — U‑bolt mounting clamp, stainless steel dimensions 50×140 mm

OEM U-bolt clamp M8 50x140 is a stainless steel U-bolt mounting clamp with M8 threaded ends and a 50×140 mm span between the legs. Designed to secure round and slightly flattened profiles to frames, brackets or flat surfaces, this clamp provides a compact threaded fixing that resists corrosion and maintains mechanical integrity in installations where a durable metal fastening is required.

Advantages

The stainless steel construction ensures resistance to rust and long service life in indoor and outdoor environments. The M8 thread is compatible with common M8 nuts and washers, enabling straightforward installation and reliable clamping force. The 50×140 mm leg spacing accommodates a wide range of pipes and tubes while the U-shape evenly distributes load around the secured profile to minimise movement and vibration.

Suitable for

• Securing metal or plastic pipes and conduit to structural frames
• Fastening tubing and rods in plumbing and HVAC assemblies
• Mounting exhaust or fuel lines in automotive and light commercial vehicles
• Attaching antenna mast or railing components in outdoor installations

Key specifications

• Material: stainless steel
• Thread size: M8
• Span between legs: 50 × 140 mm
• Shape: U-bolt with threaded straight legs
• Finish: corrosion-resistant metal surface

How to use

Place the U-bolt around the pipe, tube or rod so the legs align with the mounting surface. Insert the legs through pre-drilled holes in the bracket or surface, then fit compatible M8 nuts and washers onto the threaded ends. Tighten evenly on both sides to achieve secure contact between the clamp and the profile without over-torquing; recommended hand tools are a spanner or socket sized for M8 nuts. Verify alignment and retighten after initial load cycling if required.

Usage recommendations

For long-term outdoor use, choose stainless steel nuts and washers to match the clamp material and prevent galvanic corrosion. When securing thin-walled pipes, use a protective liner or saddle between the U-bolt and the pipe to distribute clamping pressure and avoid deformation. Regularly inspect fastenings in high-vibration applications and re-torque as needed.
