Non Sparking Double End Tubular Box Spanner by Pahwa MetalTech
Compact Tubular Spanners for Deeply Recessed Fastener Access
Pahwa MetalTech's Non Sparking Double End Tubular Box Spanner is precision-engineered for reliable, spark-free performance in the most demanding hazardous environments. Compliant with ATEX, EN, and IS standards, these tools eliminate ignition risk in oil and gas, petrochemical, pharmaceutical, mining, and explosives industries. Every tool is quality-inspected for dimensional accuracy, alloy integrity, and functional performance before delivery, ensuring Zone 0, Zone 1, and Zone 2 classified area compliance throughout service life.
Material :
Pahwa MetalTech's Non Sparking Double End Tubular Box Spanner is available in two premium non-sparking alloys: QTi® (Copper Titanium) and BronAL® (Aluminium Bronze).
QTi® offers superior hardness and tensile strength for heavy-duty applications, with a longer service life than conventional beryllium copper.
BronAL® delivers excellent corrosion resistance, ideal for marine, chemical, and humid environments. Both alloys comply with ATEX, EN, and IS non-sparking tool certifications and are non-magnetic, ensuring safety in Zone 0, Zone 1, and Zone 2 classified areas. Material test reports and special certifications are available on request.
Size and Range :
Pahwa MetalTech offers the Non Sparking Double End Tubular Box Spanner in the following specifications: 6mm to 30mm in various sizes.
The range covers the most common operational requirements for hazardous area maintenance.
All sizes are manufactured to precise tolerances for reliable fit and performance. Custom sizes and configurations beyond the standard range are available on request for specific site requirements or OEM applications. Contact Pahwa MetalTech for custom configuration enquiries.
Applications :
Pahwa MetalTech's Non Sparking Double End Tubular Box Spanner is used across critical hazardous industries.
Pipeline work, valve maintenance, instrumentation panels, pump and motor maintenance, tank wagon servicing, and equipment with deeply recessed bolts in petrochemical, oil and gas, pharmaceutical, and hazardous chemical manufacturing facilities in classified zones.
In all these applications, QTi® and BronAL® non-sparking alloys eliminate ignition risk from tool-to-surface contact, protecting personnel, equipment, and facilities. These tools help operations teams comply with OISD, PESO, ATEX, and other international safety frameworks governing classified zones.

Do's
- Select the correct end for the fastener size — each end of a double tubular spanner is a different nominal size.
- Use a T-bar or tommy bar made from non-sparking alloy through the spanner shaft hole for torque application.
- For recessed fasteners, confirm the spanner shaft clears all surrounding obstructions before inserting the T-bar.
- Keep the spanner shaft bore clean — internal corrosion can lock the T-bar inside the spanner shaft mid-job.
- Apply torque smoothly without jerking — tubular spanners are less rigid than solid spanners and can flex under shock.
- In confined spaces, use the shortest T-bar that still allows adequate torque to avoid collision with adjacent components.
- Check both socket ends for wear — the smaller end wears faster and needs earlier replacement.
- Label the nominal size on the spanner shaft using engraving rather than tape, which falls off in process environments.
Donts
- Never use a steel tommy bar with a non-sparking tubular spanner — the steel bar contacts metal and creates spark risk.
- Do not use a tubular box spanner on a fastener that is already visibly rounded — it will slip and damage further.
- Avoid applying side loads to the spanner shaft — the tube geometry resists torsion but not lateral bending well.
- Do not use a single hand on the T-bar when breaking torque — both hands prevent the bar from being ejected.
- Never use an undersized tubular spanner that rocks on the fastener — the internal socket walls will crack under torsion.
- Do not use the spanner shaft as a pipe for routing fluids, cables, or as a structural member — it will be damaged.
- Avoid using tubular spanners on fasteners that require higher torque than their size rating — use a slogging ring instead.
- Do not use a tubular spanner that shows any cracks or splits along the shaft — the tool will fail suddenly under load.
