Draper Half Moon Obstruction Ring Spanner Set - 4 Piece

They are forged from chrome vanadium steel, which is known for its strength and durability.

HI-TORQ refers to Draper's design for the ring ends, which provides a more secure grip on the fastener, reducing the chance of slippage and damage to the fastener head.

They are manufactured in accordance with DIN3113 specifications, an international standard for hand tools.

The set includes four spanners with the following sizes: 11 x 13mm, 13 x 15mm, 14 x 17mm, and 19 x 22mm.

The 'half moon' or offset shape is designed specifically to work around obstructions, allowing access to fasteners in tight or confined spaces where a straight spanner would not fit.

They are ideal for specific tasks requiring access in confined spaces. For general-purpose wrenching, standard spanners might be more versatile, but these are invaluable for specialized access.

Clean them after use with a dry cloth, store them in their wallet in a dry environment, and inspect them for damage periodically. Avoid using harsh chemicals or abrasive cleaners.

Ensure you are using the correct size spanner. Check that both the spanner's HI-TORQ ends and the fastener are clean and free from debris. Apply pressure steadily to avoid sudden jerks.

While designed for tight spaces, some obstructions may still be too severe. Try rotating the spanner or fastener slightly, or consider alternative access tools if available. Ensure the correct spanner size is selected.

Wipe away any surface rust with a fine-grade steel wool or a rust remover. Clean thoroughly and apply a light coat of oil to the surface for protection. Store in a dry place.
