Stahlwille Double Ended Open Spanner, 36x41mm size, 375mm Overall Length - 40033641


This double-ended open spanner is a precision hand tool for loosening and tightening fasteners in industrial settings. It features offset heads to give clearance when working in confined spaces and a chrome finish that aids surface durability. Designed for metric fastenings, it serves professional users across automation, electronics, electrical and mechanical trades who require a sturdy open-ended spanner for routine maintenance and assembly.

Features and Benefits:


• Chrome alloy construction provides high tensile strength and wear resistance
• Offset heads deliver a 15° opening angle for improved access
• Conforms to multiple DIN and ISO standards for consistent quality
• Double-ended design allows two common metric sizes in one tool
• Chrome finish simplifies cleaning and reduces corrosion risk

Applications


• Suitable for maintenance on industrial automation assemblies
• Ideal for fitting and removing electrical enclosures’ fasteners
• Used for mechanical plant installation and routine servicing
• Can be used in electronics workshops requiring metric fastenings
• Suitable for on-site tasks where offset access is necessary

What sizes are provided on this tool and how do they support workshop flexibility?


The spanner provides two metric jaw sizes, 36mm and 41 mm, enabling work on differently sized hex fasteners without changing tools.

How does the head geometry assist when working in restricted areas?


Each head is offset to raise the handle away from the fastener plane, and the 15° opening angle permits incremental repositioning where swing is limited.

What material properties affect longevity under repeated torque?


The tool is manufactured from chrome‑alloy steel, a material selected for strength and resistance to deformation during repeated load cycles.

Which quality standards relate to manufacturing consistency and measurement?


Production and dimensional criteria reference recognised DIN and ISO standards including ISO 10104 and ISO 7738 to ensure uniform form and fit.

Is this tool suitable for environments requiring non‑sparking equipment?


No, the construction does not provide non‑sparking characteristics and is not intended for use where spark suppression is required.
