Which size should I choose for my project?

M6 is generally suitable for light-duty fastening and thin panels. M8 is a versatile mid-range choice for furniture and general construction. M10 and M12 are typically used for heavier structural connections. Match the diameter to the load requirements and the length to your material stack-up.

M6–M12 Fully Threaded Stud Bar Rod — 304 Stainless Steel Expansion Bolt for Reliable Metric Fastening

Whether you're anchoring structural panels, assembling furniture frames, or securing equipment to concrete, finding a threaded stud rod that won't rust, strip, or fail under load is half the battle. DIYers, contractors, and fabricators who work with metric hardware know the frustration of sourcing the right diameter and length combination — and then discovering the steel is substandard. These M6–M12 fully threaded stud bar rods are built for people who need a dependable metric fastener that holds up in real-world conditions.

Each rod is machined from 304 (A2) stainless steel with full-length ISO metric coarse threading. Available in four diameters — M6, M8, M10, and M12 — and six lengths from 100mm (≈3.94") to 150mm (≈5.91"), with pack options of 1, 2, 3, or 4 pieces per order. The fully threaded design means nuts and couplers can be positioned anywhere along the shaft, giving you maximum flexibility on the job.

These stud rods are well-suited for deck and pergola construction where corrosion resistance matters, furniture and shelving assembly requiring precise metric fastening, and HVAC or electrical conduit mounting that demands vibration-resistant threaded connections. The 304 stainless steel composition makes them a go-to choice for indoor and general outdoor metric stud bolt applications.

🔩 Thread Compatibility: ISO metric coarse thread (M6, M8, M10, M12) — fits standard DIN 934 hex nuts, DIN 985 nylon lock nuts, DIN 6334 coupling nuts, and metric threaded inserts.

✅ Key Features of These Fully Threaded Stud Bar Rods

🦾 Full-Length Threading — Thread runs the entire rod length, so you can position nuts, couplers, or spacers anywhere without being locked into a fixed grip zone.
🛡️ 304 (A2) Stainless Steel Construction — Resists oxidation and surface rust in humid, wet, and general outdoor environments, keeping your fastened joints looking clean and holding strong over time.
📐 Wide Size Range — Four diameters (M6–M12) and six lengths (100–150mm / ≈3.94"–5.91") cover the most common metric stud bolt applications in one product family.
🔄 Versatile Double-End Fastening — Acts as a double-ended bolt when used with two nuts, making it ideal for through-bolting panels, joining threaded couplers, or building adjustable standoffs.
📦 Flexible Pack Quantities — Order 1, 2, 3, or 4 pieces to match your exact project needs — no overstocking, no hunting for matching hardware in different listings.
⚙️ Precise ISO Metric Thread Profile — Machined to standard metric coarse thread tolerances, ensuring smooth engagement with compatible nuts and threaded inserts without cross-threading or binding.

❓ Frequently Asked Questions

How do I choose the right length for my threaded stud rod?

Measure the total thickness of all materials being joined, then add the length needed for nuts and washers on both ends. For example, a 100mm (≈3.94") stud is typically used for joining two 40mm panels with room for hardware on each side. When in doubt, choose the next size up — you can always add a spacer or extra nut.

What is the load-bearing capacity of these stud rods?

304 stainless steel (A2) generally has a tensile strength of around 500–700 MPa. Actual load capacity depends on the diameter, thread engagement length, and installation conditions. M6 is typically rated for lighter loads, while M12 handles significantly heavier structural connections. For safety-critical applications, consult a structural engineer.

Can these be used outdoors or in wet environments?

Yes. 304 stainless steel offers good corrosion resistance in most outdoor and humid environments, including decks, pergolas, and covered outdoor structures. It is generally not recommended for direct saltwater or marine exposure — for those conditions, 316 stainless steel is typically the better choice.

What thread standard do these stud rods use, and what nuts are compatible?

These studs use standard ISO metric coarse threads (M6, M8, M10, M12) per DIN 975. They are compatible with standard metric hex nuts (DIN 934), nylon lock nuts (DIN 985), coupling nuts (DIN 6334), and metric threaded inserts. They are not compatible with SAE/imperial hardware.

Are these fully threaded along the entire length?

Yes. These are fully threaded stud bar rods — the thread runs the entire length of the rod with no unthreaded shank. This gives you maximum flexibility for positioning nuts and couplers anywhere along the shaft, which is especially useful for adjustable standoffs and through-bolt assemblies.

Which diameter should I choose for my project?

M6 is generally suitable for light-duty fastening, thin panels, and furniture assembly. M8 is a versatile mid-range choice for general construction and shelving. M10 and M12 are typically used for heavier structural connections such as deck framing, equipment mounting, and load-bearing joints. Match the diameter to your load requirements and the length to your material stack-up.

Can I cut these stud rods to a custom length?

Yes. Stainless steel threaded rods can generally be cut with a hacksaw, angle grinder, or bolt cutter. After cutting, use a thread-cleaning die (matching the rod's diameter and pitch) to restore the thread end for clean nut engagement. Always deburr the cut end before use.
