Key Features and Benefits

• Withstands Demanding Use: Chrome vanadium steel handles high torque without bending or deforming under load.
• Guards Against Rust: Nickel chrome plating protects against rust and corrosion in damp or outdoor conditions.
• Two Sizes Per Tool: The double open ended design means each spanner covers two different metric sizes.
• Side Access to Fasteners: Open jaws slide onto nuts and bolts from the side, useful where a ring spanner cannot be fully positioned.

• Reposition if Needed: Lift and reposition the spanner if movement is restricted by surrounding components.

• Store After Use: Return each spanner to the plastic rack to keep the set complete.

Frequently Asked Questions (FAQs)

• What is the difference between an open ended spanner and a ring spanner?
  An open ended spanner grips two flat sides of a nut or bolt, letting you slide it on from the side. A ring spanner encircles the full fastener head, providing a more secure grip at higher torque. Open ended spanners work better in confined spaces where a ring cannot be fully positioned.

• What does "double open ended" mean on a spanner?
  Each spanner has two open jaws, one at each end, each sized for a different fastener. One tool therefore covers two metric sizes, reducing the number of spanners you need to carry.

• What is chrome vanadium steel?
  Chrome vanadium (CrV) is a steel alloy containing chromium and vanadium. These elements increase the strength and toughness of the steel. CrV spanners handle high torque without deforming, and the chromium content adds resistance to corrosion.

• Can open ended spanners round off nuts?
  There is a greater risk compared to ring spanners, particularly under high torque, because the jaw contacts only two faces of the fastener. Selecting the correct size and seating the jaw fully on the nut before applying force reduces this risk considerably.

• What metric spanner sizes are needed for general automotive and mechanical work?
  Most fasteners encountered in automotive, household, and general mechanical tasks fall between 8mm and 19mm. A set spanning 6mm to 22mm covers the large majority of metric nut and bolt sizes found in everyday work.

Summary

The Blue Spot Tools 8 Piece Metric Double Open Ended Spanner Set gives you eight chrome vanadium spanners covering paired sizes from 6mm to 22mm. A nickel chrome mirror-polished finish protects against rust and corrosion, and the plastic storage rack keeps the set together. Blue Spot Tools backs this set with their lifetime guarantee.
