Draper Expert Deep Ring Spanner Metric

The Draper Expert 36mm x 41mm Bi-Hexagon Deep Offset Ring Spanner bridges the gap between medium and large metric fasteners, making it an essential tool for heavy automotive and industrial applications. This double-ended configuration combines two complementary sizes that are frequently specified in commercial vehicle maintenance, agricultural machinery, and plant equipment servicing. The 36mm opening pairs perfectly with the smaller end of this range, whilst the 41mm size covers larger bolt heads and nuts. Manufactured from forged chrome vanadium steel, this spanner benefits from the enhanced reach provided by its long pattern design, allowing access to deeply recessed fasteners that standard spanners cannot reach. The bi-hexagon profile engages across six flats rather than two corners, distributing applied torque more evenly and virtually eliminating the risk of rounding off expensive fasteners. The 15° cranked ring ends provide improved knuckle clearance and allow the tool to be repositioned for ratcheting action in restricted spaces. Heat-treated through hardening and tempering, this spanner maintains its structural integrity even under extreme working loads. The chrome-plated and fully polished finish not only looks professional but also resists corrosion and makes the tool easy to wipe clean.
