High-Tensile Structural Bolts Manufacturer, Wholesaler, Supplier & Exporter to Philippines
Structural steel connections rely on high-strength friction-grip (HSFG) bolt, nut, and washer assemblies rated to precise proof loads. We manufacture and export these to ASTM A325, ASTM A490, and IS 3757 for steel-structure fabricators and EPC contractors. The Philippines' active construction sector imports fasteners through the Port of Manila for distribution across Luzon, Visayas, and Mindanao.

Duty and tax rates change and transit depends on carrier, routing, and port congestion, so figures marked indicative are confirmed against your product and destination port when we quote. Your customs broker should verify final landed cost.
High-strength friction-grip bolting works on a principle that surprises people outside structural engineering: the joint doesn't primarily rely on the bolt shank resisting shear at all. Instead, the bolt clamps the connected plates together so tightly that friction between the plates themselves transfers the load — which is why installation torque (or the direct-tension method used to verify it) matters as much as the bolt's material grade.

- • Typhoon-resistant structural design in the Philippines often specifies hot-dip galvanized structural and anchor bolts.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 60,000-100,000 sets of high-tensile structural bolt assemblies (bolt, nut, washers) in common sizes (M16-M20). Exact quantity depends on size and grade and is confirmed at quote time.
You don't need a full container to order. Hurain Engitech & Trade — the group Global Fasteners Exports operates under — regularly ships smaller, partial-container (LCL) orders of just a few pallets or boxes for buyers who don't yet need FCL volume, consolidated with other cargo to keep freight cost reasonable.
Where Philippines Buyers Use High-Tensile Structural Bolts
High-rise and industrial steel frames
Beam-to-column and truss connections requiring certified friction-grip performance.
Bridge and infrastructure connections
High-load structural joints in bridges and heavy infrastructure.
Lattice towers and transmission structures
Bolted connections in towers subject to significant wind and dynamic loading.
Common Mistakes Buyers Make
Substituting A490 for A325 without checking the spec
A490 bolts have restrictions (including on galvanizing) that don't apply the same way to A325 — check the actual structural specification before substituting.
Under-torquing a friction-grip connection
The joint relies on clamping force generating friction between plates — under-torqued bolts undermine the entire friction-grip design intent, not just the bolt itself.
Mixing bolts from different heat lots without tracking
Structural sign-off typically requires heat-number traceability — mixing lots without recording it can invalidate the QA paper trail.
Key Terms
- Friction-grip connection
- A bolted joint design where clamping force generates friction between plates to transfer load, rather than relying primarily on bolt shear.
- Direct tension indicator (DTI)
- A washer with crushable protrusions used to verify a structural bolt has reached its specified installation tension.
- Hydrogen embrittlement
- A brittleness that can be introduced into high-strength steel during certain plating or galvanizing processes — a key reason A490 bolts restrict some finishing methods.
How Ordering Works
- 1
Send your requirement
Product, grade/standard, quantity, and your preferred Incoterm (FOB/CIF/CFR).
- 2
Receive a quote
We confirm price, lead time, and MOQ based on ready stock or manufacturing time.
- 3
Sample & confirm (optional)
For new buyers, we can arrange samples before the full order is confirmed.
- 4
Production, QC & shipping
Manufacturing or sourcing, batch inspection, export documentation, and container loading.
HS Code & Customs Classification
Most fasteners fall under HS Chapter 73 (articles of iron or steel) or Chapter 74/76 for brass and aluminum items — the exact 8-10 digit subheading depends on the specific product and material. We include the HS code on the commercial invoice; confirm the applicable import duty with your customs broker, since rates vary by country and trade agreement.
