Category Overview

What Are Weld Studs & Fasteners

Weld studs and fasteners are the structural core of stud arc welding — headed pins and threaded studs that are fused directly to a steel base plate in a fraction of a second, creating a bond that transfers shear load, anchors insulation, or mounts hardware without a single drilled hole or bolted connection.

This category covers the full range our factory produces on one production floor: headed shear studs for composite steel-concrete decks, threaded and non-threaded weld studs for equipment fabrication, wear-resistant studs for abrasive environments, and insulation pins for thermal anchoring. Every item is cold-headed from certified steel coil, heat-treated to the required mechanical grade, and gauge-checked before it reaches packing — so the diameter, length, and tensile rating on your purchase order match what arrives on site, batch after batch.

Structural Bonding Core

Each stud is arc-welded base-to-plate in under a second, fusing a full-strength metallurgical bond that outperforms bolted connections in shear — giving your structural design a fastening method it can rely on without maintenance.

Material & Grade Versatility

Mild carbon steel, 304 and 316L stainless, and galvanized finishes are all produced on the same lines — so a mixed bill of materials for corrosive, structural, and cosmetic applications ships from one order instead of three suppliers.

Standards Compliance

Geometry, tensile strength, and weld collar dimensions are held to AWS D1.1, EN ISO 13918, and ASTM A29 across the whole range — so your project's authority submission and third-party inspection clear on the first pass.

One-Stop Category Range

Shear studs, threaded studs, wear studs, and insulation pins are stocked and produced side by side — so a single inquiry covers every fastener type your bill of materials calls for, with one lead time and one shipment.

01
Identify Your Application

Structural, fastening, wear, or insulation — start with the function the stud needs to perform on your project.

02
Confirm Load & Base Material

Shear load, pull-out force, and base plate thickness determine the diameter, length, and material grade required.

03
Check Required Standard

Confirm whether your project specification calls for AWS, EN, ASTM, or CE compliance before finalizing your order.

04
Send Us Your Drawing

Our engineering team confirms the exact product code and issues a detailed quotation within 24 hours.

Still unsure which product line fits your drawing? Our engineers will confirm it in writing at no cost.

Specifications & Materials

Every dimension and material grade below is held to the same in-house inspection process — so what you specify on the purchase order is exactly what leaves the factory floor.

Diameter Range

Ø6mm to Ø32mm across the category, covering everything from fine threaded studs to heavy structural shear studs — one range spanning every load class.

Length Range

From 20mm short-cycle CD studs up to 300mm shear studs, produced to a tolerance tight enough that welded height stays consistent slab to slab.

Mechanical Grade

Tensile and yield strength verified batch-by-batch through in-house testing, with certificates referencing heat number for full traceability on request.

Surface Finish

Plain, zinc-plated, hot-dip galvanized, or passivated stainless finishes — matched to your project's corrosion exposure without a change in lead time.

Standards Compliance

AWS D1.1, EN ISO 13918, ASTM A29, and CE coverage across the range, with documentation issued alongside every shipment for authority submission.

Packaging & Traceability

Each carton is labeled with product code, heat number, and quantity, and can carry your private label — so warehouse receiving never has to guess.

Mild Carbon Steel Standard structural and fastening grade
Stainless 304 / 316L Corrosive and marine environments
Galvanized / HDG Extended outdoor corrosion resistance
High-Strength Boron Steel Wear and high-load applications

Why This Category

Features That Protect Your Project Timeline

Every feature below exists to remove a specific risk from your procurement — the kind of risk that shows up as a failed inspection or a delayed pour, not as a line item on a quote.

01
Consistent Cold-Heading Tolerance

Automated gauging holds diameter and length to ±0.3mm on every run, so stud height stays uniform across every floor and your inspector never flags a dimensional deviation.

02
In-House Heat Treatment

Furnace cycles are set and logged per material grade in-house rather than outsourced, guaranteeing the tensile and yield strength your structural calculation assumed is what actually welds to the plate.

03
Full Standards Coverage

AWS D1.1, EN ISO 13918, ASTM A29, and CE compliance run across the whole product line, not just the flagship item — so whichever regional code your project cites, your submission clears review the first time.

04
Multi-Material Production Line

Mild steel, stainless, and galvanized studs run on the same certified process — so a mixed bill of materials ships as one consolidated order instead of being split across separate suppliers.

05
Batch Traceability

Every carton is tagged with a heat-number reference, so if a question ever arises on site, we can trace it back to the exact production run and material certificate within hours, not weeks.

06
Flexible MOQ & Fast Sampling

Trial orders and first-article samples are dispatched within 7–14 days, so you can verify fit and quality on a live project before committing to a full production quantity.

See how these features translate into savings on your specific project.

Ask Our Engineers
What diameter and length range does this category cover?
Across the six product lines in this category, diameters run from Ø6mm to Ø32mm and lengths from 20mm to 300mm. Headed Shear Studs — our flagship, fully published product — covers Ø13–25mm in lengths from 50mm to 300mm. Other lines fall within the same overall range but vary by product type; send your drawing and we will confirm exact availability within 24 hours.
What is the minimum order quantity for this category?
Standard MOQ for catalogue products is 1,000 pieces per item, with flexibility for first-time trial orders so you can verify quality before a full commitment. OEM and non-standard configurations carry a separate MOQ confirmed at quotation stage based on tooling requirements.
Can I mix products from different lines in one order?
Yes. Since every product line in this category runs on the same production floor, shear studs, threaded studs, wear studs, and insulation pins can be combined into a single purchase order and a single shipment — simplifying your logistics and consolidating your documentation into one set of certificates.
What certifications and test reports come with each order?
Every batch ships with an in-house dimensional inspection report and mechanical test data referencing heat number for traceability. Third-party independent lab certificates are available on request and are standard practice for orders destined for structural authority submissions under AWS, EN, or ASTM frameworks.
How long is production lead time for standard versus custom items?
Catalogue products typically ship 7–15 business days after order confirmation and deposit. Custom or OEM configurations add 10–15 working days for sample production and approval when new tooling is required, and run at standard lead time once tooling is already on file.
Can you produce non-standard sizes or private-label packaging?
Yes, across every product line in this category. Non-standard diameters, lengths, thread profiles, and material grades are supported with sample approval before bulk production, and private-label carton printing and pallet configuration are available for distributor and reseller orders subject to a minimum quantity.
