304 Stainless Steel U-Bolts — Reliable Pipe Clamping for M6, M8, M10 & M12 Applications

Whether you're securing exhaust pipes under a vehicle, anchoring conduit runs in a workshop, or fastening round tubing on a rack or fence post, a loose or corroded U-bolt can mean a failed connection at the worst possible moment. These 304 A2 stainless steel U-bolts are built for DIYers, mechanics, and tradespeople who need a dependable metric pipe clamp screw that won't rust out after a season outdoors.

Each U-bolt is machined from solid 304 (A2) stainless steel rod and ships with matching metric hex nuts. Thread diameters span M6 (×1.0 pitch), M8 (×1.25 pitch), M10 (×1.5 pitch), and M12 (×1.75 pitch). Pipe diameter (inside span) ranges from 14mm (≈9/16") up to 328mm (≈12.9"), covering a wide range of pipe and tube sizes. Available in quantities of 1, 2, 4, 5, 6, 8, 10, 20, or 40 pieces per order — buy exactly what your project needs.

Typical use cases include automotive exhaust and suspension work (M8–M10 U-bolts for pipe clamping), plumbing and conduit support brackets (M6–M8 for lighter pipe runs), marine dock hardware and boat rigging (where 304 SS corrosion resistance matters), and structural racking or shelving systems that use round tube framing (M10–M12 for heavier spans).

🔩 Thread Compatibility: Standard ISO metric coarse thread — M6×1.0 / M8×1.25 / M10×1.5 / M12×1.75. Compatible with standard metric hex nuts and flat washers of the same pitch.

✅ Key Features of These 304 Stainless Steel U-Bolts

  • 🦀 Corrosion-Resistant 304 A2 Stainless Steel — Resists rust, oxidation, and mild chemical exposure, making these U-bolts a solid choice for outdoor pipe clamping, coastal environments, and wet workshop conditions.
  • 📐 Wide Size Range in One Listing — Thread diameters from M6 to M12 and pipe spans from 14mm (≈9/16") to 328mm (≈12.9") cover the majority of residential, automotive, and light industrial pipe clamp screw applications.
  • 🔧 Metric Coarse Thread for Easy Fastening — Standard ISO metric thread pitches (M6×1.0 through M12×1.75) mean these U-bend screws thread smoothly onto any compatible metric nut without cross-threading risk.
  • 📦 Flexible Quantity Options — Order 1 piece for a quick repair or up to 40 pieces for a larger installation run. Bulk pricing scales down per-unit cost, so you're not paying single-piece rates for multi-bolt jobs.
  • ⚙️ Includes Matching Hex Nuts — Each U-bolt ships with the corresponding metric hex nuts, so you have everything needed to mount and tighten without a separate hardware run.
  • 🏗️ Versatile U-Bend Design — The U-shaped profile distributes clamping force evenly around round pipe or tube, reducing point-load stress compared to single-bolt clamps — useful for exhaust hangers, conduit brackets, and round-tube rack systems.

⚠️ Size Tip: The "Pipe Dia" in the variant name refers to the inside span of the U-bolt — measure your pipe's outer diameter (OD) and match it to the closest pipe dia option. When between sizes, size up for easier installation.

❓ Frequently Asked Questions

How do I choose the right U-bolt size and pipe diameter?

Measure the outer diameter (OD) of the pipe or round object you need to clamp. The "Pipe Dia" in the variant name (e.g., 14mm, 22mm, 60mm) refers to the inside span of the U-bolt — it should match or be very close to your pipe OD. For thread diameter, M6 is typically used for lighter loads, M8–M10 for medium applications, and M12 for heavy-duty structural work. When in doubt, size up. Quick inch conversions: 14mm ≈ 9/16", 22mm ≈ 7/8", 33mm ≈ 1-5/16", 60mm ≈ 2-3/8", 90mm ≈ 3-1/2".

What load can these U-bolts handle?

Load capacity depends on the thread diameter, material grade, and installation method. Generally, M6 U-bolts are suited for light-duty clamping, M8 for moderate loads, M10 for heavier applications, and M12 for structural or high-tension use. 304 stainless steel has a tensile strength of typically 515 MPa (≈75,000 psi). Always consult a licensed engineer for safety-critical or load-bearing installations.

Are these U-bolts suitable for outdoor or marine use?

Yes, for most outdoor applications. 304 (A2) stainless steel offers good resistance to rust, oxidation, and mild corrosive environments including rain, humidity, and coastal air. For highly aggressive marine environments with prolonged saltwater immersion or heavy chloride exposure, 316 (A4) stainless steel is generally recommended instead.

What thread standard do these U-bolts use — are they compatible with standard nuts?

These U-bolts use standard ISO metric coarse threads: M6×1.0, M8×1.25, M10×1.5, and M12×1.75. They are compatible with any standard metric hex nut, flange nut, or lock nut of the same thread size and pitch. They are not compatible with UNC/UNF (inch) threads.

Do the U-bolts come with nuts included?

Yes, each U-bolt in this listing typically ships with matching metric hex nuts. Please refer to the product images for your specific variant to confirm the included hardware. If you need additional nuts or washers, contact us before ordering.

How do I convert the pipe diameter from mm to inches?

Divide the mm value by 25.4 to get inches. Common conversions for this listing:

  • 14mm ≈ 0.55" (≈ 9/16")
  • 22mm ≈ 0.87" (≈ 7/8")
  • 27mm ≈ 1.06" (≈ 1-1/16")
  • 33mm ≈ 1.30" (≈ 1-5/16")
  • 42mm ≈ 1.65" (≈ 1-5/8")
  • 60mm ≈ 2.36" (≈ 2-3/8")
  • 76mm ≈ 3.00" (≈ 3")
  • 90mm ≈ 3.54" (≈ 3-1/2")
  • 114mm ≈ 4.49" (≈ 4-1/2")
  • 220mm ≈ 8.66" (≈ 8-5/8")
  • 328mm ≈ 12.91" (≈ 12-7/8")
Which size should I choose for a standard 1-inch or 1-1/4 inch pipe?

A standard 1" nominal pipe has an OD of approximately 33.4mm — the M6×1×33mm or M8×1.25×34mm variants are generally the closest match. A 1-1/4" nominal pipe has an OD of approximately 42.2mm — the M8×1.25×42mm or M10×1.5×42mm variants are typically the right fit. Always measure your actual pipe OD before ordering, as nominal pipe sizes do not equal actual OD.
