Overview:

This Blue Spot Tools 8 Piece Metric Deep Offset Ring Spanner set covers paired sizes from 6mm to 22mm. Each spanner is manufactured from chrome vanadium steel and finished with a nickel chrome mirror-polished coating for corrosion resistance.

The deep offset design raises each ring head above the handle. This gives access to recessed or obstructed fasteners that a flat-handled spanner cannot reach. All eight spanners sit in an included plastic storage rack.

The rack keeps each size in order and makes the set straightforward to carry between jobs. The set carries the Blue Spot Tools lifetime guarantee.

What's Included

• 8 Deep Offset Ring Spanners:
  • 6x7mm
  • 8x9mm
  • 10x11mm
  • 12x13mm
  • 14x15mm
  • 16x17mm
  • 18x19mm
  • 20x22mm

Key Features and Benefits

• Chrome Vanadium Construction: The alloy resists deformation under load and maintains hardness through repeated use.
• Nickel Chrome Mirror-Polished Finish: The plated coating protects against rust and corrosion in workshop and automotive environments.
• Deep Offset Ring Heads: The angled offset raises each ring above the handle plane, giving reach into recessed fasteners and tight spaces.
• Double-Ended Design: Each spanner carries two sizes, so eight pieces cover sixteen different nut and bolt dimensions.
• Plastic Storage Rack: Holds all eight spanners for quick selection and safe transport between jobs.

Typical Applications

• Automotive engine and suspension work where bolts sit in recessed positions
• Mechanical maintenance on machinery with obstructed fasteners
• General workshop and garage nut and bolt work
• Agricultural and plant machinery servicing
• Plumbing and pipework where standard spanners cannot reach
• General trade and on-site maintenance tasks

How to Use

• Select the Correct Size: Match the ring end to the nut or bolt head before applying any force.

• Position the Spanner: Slide the ring over the fastener until it seats fully and squarely.

• Apply Torque: Turn the handle in the required direction - clockwise to tighten, anti-clockwise to loosen.

• Reposition as Needed: In confined spaces, lift the spanner clear, rotate it, and reseat to continue turning.

• Store After Use: Return each spanner to the plastic rack to keep the set complete and ready for next use.

Frequently Asked Questions (FAQs)

• What does "deep offset" mean on a ring spanner?
  A deep offset ring spanner has ring ends set at an angle to the handle. This raises the ring head significantly above the work surface, giving access to recessed or obstructed fasteners that a flat-handled spanner cannot reach.

• What advantage does an offset ring spanner offer over a standard ring spanner?
  The angled design gives better access to fasteners in tight or awkward spaces. It also provides clearance for knuckles, reducing the risk of injury when working in confined areas.

• What is chrome vanadium steel?
  Chrome vanadium (Cr-V) steel is an alloy combining chromium and vanadium with carbon steel. The composition improves hardness, toughness, and resistance to wear, abrasion, and corrosion. This makes it a widely used material for professional hand tools.

• What is the difference between a ring spanner and an open-end spanner?
  A ring spanner has a fully enclosed loop that surrounds the fastener. This gives a more secure grip and reduces the risk of rounding bolt heads. An open-end spanner grips two flats only and can slip under high torque. Ring spanners are generally preferred where higher torque or confined access is involved.

• Can metric ring spanners be used on imperial nuts and bolts?
  No - metric and imperial sizes are not interchangeable. Using a metric spanner on an imperial fastener, or vice versa, risks damaging the fastener head. Always match the spanner size to the fastener specification.
