Open End Fix Spanner:21 x 23 - DIN 3110/No. 6

This open end spanner is sized at 21 x 23 millimetres and conforms to the DIN 3110 standard. It features a dual-ended design, allowing a single tool to handle two different fastener sizes to reduce the number of implements required in a toolkit. The designation indicates it is a number 6 spanner, which is a standard reference for this size range within the DIN 3110 series. Buyers typically select this specific size and standard to ensure precise fitment with corresponding hexagonal nuts and bolts. To choose the correct tool, verify that the fastener size matches either the 21 or 23 millimetre opening, confirming compatibility with the DIN 3110 specification before purchase.
