Key Features & Specifications
- Material Excellence: Made of heat-treated 45# medium carbon steel (hardness HRC 40–48) for superior strength and wear resistance.
- Precision Ground: Each hexagonal endpoint is CNC-ground to ensure a snug fit on 30 mm fasteners, minimizing rounding risks.
- Optimized Length: 260 mm (10.2 inch) handle provides balanced leverage for high-torque applications without excessive bulk.
- Single Box-End Design: One closed-end hexagonal socket (30 mm) prevents slippage and allows full 360° rotation in limited access areas.
- Surface Treatment: Anti-corrosion black oxide coating (optional chrome plating available upon request) extends service life in humid or oily environments.
- Ergonomic Handle: Straight shaft with a knurled grip pattern for non-slip handling, even with greasy hands.

Why Choose Our 30×260 mm Straight Hex Wrench?
This tool is specifically engineered for heavy-duty applications where standard wrenches fail. The single box-end design gives you a full 360-degree swing arc without needing to reposition – ideal for tightening or loosening bolts in recessed areas. The 45# steel construction ensures the wrench can withstand repeated impact without deformation, while the precise hexagonal contour transmits force evenly to prevent fastener damage.
Customer Benefits:
- Reduce downtime with a tool that fits perfectly and reduces rounding of bolt heads.
- Extend tool replacement cycles thanks to hardened steel and anti-rust coating.
- Save storage space – one single-ended wrench takes less room than a set of combination wrenches.
- Customize your order with laser engraving for branding or size marking (available upon request).

Frequently Asked Questions (FAQ)
-
Q: Is the 30 mm size exactly 30 mm or does it have a tolerance?
A: The hexagonal opening is machined to a tolerance of ±0.05 mm, ensuring a snug fit on standard 30 mm hex bolts (ANSI/ISO compatible). -
Q: Can I use this wrench for impact applications?
A: While designed for manual use, the 45# steel construction can withstand moderate impact from a hammer or mallet. For heavy impact, we recommend upgrading to a chrome-moly alloy variant (available upon request). -
Q: What is the surface coating? Will it rust easily?
A: Standard finish is black oxide, which offers moderate corrosion resistance. For harsh environments, we can apply a zinc-plated or phosphate coating after consultation. -
Q: Do you offer this wrench in other handle lengths for the same 30 mm hex?
A: Yes, we can customize overall length from 200 mm to 400 mm. Minimum order quantities may apply for non-standard lengths. -
Q: What packaging options do you provide?
A: Common options include polybag with header card, blister pack, clamshell, or bulk box. Private label (customer logo) is also available. -
Q: How do I clean and maintain this wrench?
A: Wipe with a clean cloth after use; occasionally apply a light rust-preventive oil on the surface. Avoid prolonged exposure to strong acids or alkalis. -
Q: What is the minimum order quantity (MOQ)?
A: For stock sizes (30 mm × 260 mm), MOQ is 500 pcs. For custom dimensions or special finishes, MOQ is 1000 pcs. -
Q: Do you have any certifications for quality management?
A: Our factory operates under an internal quality control system. While we do not claim third-party certifications unless explicitly listed, we follow standard manufacturing practices (ISO 9001 principles are implemented). Please contact our sales team for specific compliance documents upon request.
