M6 M8 M10 U-Bolt with Plate and Nut — Stop Guessing Sizes, Get the Right Stainless Steel Clamp the First Time

Pipe clamps that are a hair too wide rattle under vibration. Bolts that are a millimeter too short leave the nut barely threaded. And zinc-coated hardware that looked fine at the store shows rust streaks within a season outdoors. If you have been through that cycle, these M6 M8 M10 stainless steel U-bolts are designed to end it — 40 distinct size combinations in one listing, all in 304 stainless, available in 1, 2, 4, or 10-piece packs so you order exactly what the job needs.

Each Plates and Nuts set ships as a complete assembly: one U-bolt formed from 304 stainless steel rod, one flat saddle plate, and two matching hex nuts — nothing extra to source. Thread sizes cover M6, M8, and M10 with metric coarse pitch (ISO standard). Inside widths run from 20mm (approx. 13/16 in.) to 105mm (approx. 4-1/8 in.), and leg lengths from 45mm (approx. 1-3/4 in.) to 200mm (approx. 7-7/8 in.), spanning the range from small conduit clamps to heavy trailer axle hardware.

These U-bolts see regular use in trailer leaf spring and axle clamping, exhaust and pipe bracket mounting, marine dock and rack hardware, and custom steel fabrication — anywhere a corrosion-resistant stainless U-bolt with plate and nut needs to hold tight without maintenance headaches.

🔩 Size Format: All sizes follow Thread x Inside Width x Leg Length in mm (e.g., M8x40x90 = M8 thread, 40mm inside width, 90mm legs). Variants labeled Plates and Nuts include the full hardware set. Variants without that label are U-bolt only. Confirm your variant name before ordering.

✅ Key Features of These M6 M8 M10 Stainless Steel U-Bolts

🦀304 Stainless Steel — No Rust Streaks — The U-bolt, plate, and nuts are all 304 stainless, resisting oxidation in outdoor, coastal, and wet environments where zinc or carbon steel hardware typically fails within one to two seasons.
📐40 Sizes, One Listing — Inside widths from 20mm to 105mm and leg lengths from 45mm to 200mm cover light conduit clamps through heavy trailer axle U-bolts, eliminating the need to source from multiple suppliers for a single project.
🔧Ready-to-Install Hardware Set — Plates and Nuts variants include the U-bolt, flat saddle plate, and two hex nuts in one pack. No hunting for matching hardware — everything threads together straight out of the bag.
⚙ISO Metric Coarse Thread — Wrench-Ready — M6 (1.0mm pitch), M8 (1.25mm pitch), and M10 (1.5mm pitch) follow ISO metric coarse standards, compatible with any standard metric socket set and torque wrench for consistent, repeatable installation.
📦1, 2, 4, or 10-Piece Packs — Order a single replacement set or a 10-pack for a full trailer build. Larger packs are priced at a lower per-piece cost, making bulk stainless U-bolt orders practical for fabricators and fleet maintenance shops.
🔴Uniform Bend Radius for Even Clamping — The U-bolt is formed with a consistent radius that seats flush against round pipe or bar stock, distributing clamping load evenly and reducing the risk of point-loading or deforming thin-wall tubing during tightening.

⚠ Before You Order: Measure your pipe or bar outside diameter (OD) first. Select the inside width that matches or is 1–2mm larger than the OD for a snug fit. Leg length must be long enough for the plate and both nuts to seat fully with thread engagement — when in doubt, size up on leg length.

❓ Frequently Asked Questions

How do I read the size code on these U-bolts?

The format is Thread Diameter x Inside Width x Leg Length, all in mm. For example, M8x40x90 means an M8 thread, 40mm inside width (the gap the pipe sits in), and 90mm leg length. Match the inside width to your pipe or bar outside diameter. When the pipe OD falls between two sizes, choose the larger inside width for easier fit and installation.

What is the difference between the Plates and Nuts variants and the plain variants?

Variants labeled Plates and Nuts include the U-bolt, one flat saddle plate, and two hex nuts as a complete ready-to-install assembly. Variants without that label include the U-bolt body only — useful if you already have matching hardware. Check the variant name carefully before adding to cart, and contact us if you need clarification on a specific size.

Are these U-bolts rust-proof for outdoor and marine use?

304 stainless steel offers good corrosion resistance in outdoor, coastal, and mildly marine environments and is generally suitable for most outdoor fastening applications. It is not fully immune to corrosion in prolonged seawater immersion or highly aggressive chemical environments — in those cases, 316 stainless steel is typically the recommended upgrade for longer service life.

What thread pitch do these U-bolts use — will standard metric nuts fit?

These U-bolts use standard ISO metric coarse thread: M6 at 1.0mm pitch, M8 at 1.25mm pitch, and M10 at 1.5mm pitch. The included nuts match these pitches exactly. They are also compatible with standard metric hex nuts, nylon lock nuts, and washers available at any hardware store or industrial supplier.

Can I use these for trailer axle or leaf spring clamping?

Yes, these U-bolts are commonly used in trailer axle and leaf spring clamping applications. Select the inside width that matches your axle tube OD and a leg length that allows the plate and both nuts to seat with full thread engagement. For safety-critical suspension use, always verify dimensions against your trailer manufacturer specifications and torque fasteners to the recommended value.

How do I convert the mm leg length to inches?

Divide the mm value by 25.4. Quick reference for common sizes in this listing:

45mm = approx. 1-3/4 in.
70mm = approx. 2-3/4 in.
100mm = approx. 3-15/16 in.
120mm = approx. 4-23/32 in.
140mm = approx. 5-1/2 in.
200mm = approx. 7-7/8 in.

What quantity options are available and how are they priced?

Each size is available in 1pcs, 2pcs, 4pcs, and 10pcs packs. Larger quantity packs are priced at a lower per-piece cost, making them practical for bulk trailer builds, fabrication shops, or maintenance stock. Select the Amount option on the product page to compare pricing across pack sizes before adding to cart.

What is the load capacity of M6, M8, and M10 U-bolts?

Load capacity varies by thread size, leg length, installation torque, and the specific application. Generally, M6 is suited for light-duty clamping, M8 for medium structural loads, and M10 for heavier applications such as large-diameter pipe mounting or trailer axle hardware. For any load-bearing or safety-critical installation, consult a qualified engineer and verify against the working load requirements of your specific project.
