Engineeredto hold.
Industrial-grade bolts, nuts, and fasteners — certified, traceable, and engineered to standard. From M3 to structural.
Know every dimension.
Every NEXBOLTS line is drawn to standard — head, shank, thread, and drive dimensioned and traceable. This is the language printed on every datasheet we ship.
Head
Bearing face and wrench flats — sized across-flats (A/F).
Shank
Unthreaded grip length (Ls) that carries shear.
Thread
Pitch (P) over nominal diameter (ØD); coarse or fine.
Drive
Hex, socket, Torx, or slot — the tooling interface.
Built for what you build.
From foundations to flight hardware, the same catalog answers wildly different loads, environments, and standards.
Construction
Structural steel, concrete anchoring, and timber connection at scale.
Typical grade: ASTM A325 / F1554 Gr 55
Automotive
High-volume, vibration-resistant joining for chassis and driveline.
Typical grade: Class 10.9 / SAE Grade 8
Aerospace
Flight-critical, traceable fasteners in titanium and superalloy.
Typical grade: Ti-6Al-4V / A286 (160–180 ksi)
Marine
316 and duplex stainless engineered against salt and chloride.
Typical grade: A4-80 (316) / Duplex
Oil & Gas
Pressure-rated studding and bolting for flanges and wellheads.
Typical grade: ASTM A193 B7 / A194 2H
OEM & Assembly
Engineered fastening programs for production lines.
Typical grade: Class 12.9 / A2-70

Grades and materials for every load.
Carbon to titanium, Class 4.6 to 12.9 — matched to load, corrosion, and temperature. The full matrix, the way an engineer reads it.
Standard isn't the limit.
When the catalog stops, manufacturing starts — special runs, kitting, and managed inventory built around your line.
Custom Manufacturing
Special parts to print — non-standard sizes, heads, and materials.
- Made-to-print specials from sample or drawing
- Non-standard diameters, lengths, and thread forms
- Exotic materials — titanium, Inconel, duplex, brass
- Custom head, drive, and point geometries
Kitting & Assembly
Line-side kits, sub-assemblies, and packaged hardware sets.
- Bill-of-material kitting to your part numbers
- Pre-assembled bolt, nut, and washer stacks
- Barcoded, labelled, and sequenced packaging
- Custom bag, blister, and box counts
Vendor-Managed Inventory
Stocking programs that keep bins full and lines running.
- Bin, drawer, and silo scanning and replenishment
- Min/max and Kanban two-bin programs
- Consignment stock with usage-based billing
- Demand forecasting and usage reporting
Bulk & Wholesale
Volume pricing and reliable supply for distributors and trade.
- Volume and blanket-order pricing
- Drum, keg, and bulk-carton quantities
- Scheduled releases against forecast
- 24-hour dispatch on stocked lines
Certified down to the thread.
Quality isn't a stamp at the end — it's a documented chain from mill to dispatch, with the certificates to prove it.
