Steel strapping. Three jobs. One manual tool.
Tension, form a sealless joint and cut the strap with the A333. This manual steel strapping tool helps you secure flat packages, crates and suitable pallet loads without a separate metal seal, battery or compressed-air connection.
-
Fewer tool changes: combine tensioning, joint formation and cutting in one tool.
-
No separate metal seals: the overlapping steel strap forms the joint, removing one consumable from your packing routine.
-
Work where the load is: manual operation suits warehouses, dispatch areas and locations without power or air.
Check your steel strap before ordering
Current A333 configuration: factory setup for nominal 3/4-inch steel strap. The A333 range covers 12.7โ19 mm widths, but the guide and tool setup must match your actual strap. Do not assume one setup accepts every width without adjustment.
For 1/2-inch, 5/8-inch or metric stock, email sales@iwiss.com with the measured width, thickness, steel grade/tensile strength and a photo of the package so we can help check suitability before purchase.
Built for practical industrial packing
-
Warehouses and dispatch: strap crates, cases and suitable rigid pallet loads at the packing location.
-
Metal fabrication: bundle suitable metal sections and components with a flat surface for tool placement.
-
Timber and building materials: secure suitable boards and rigid packaged materials; use edge protection where needed.
-
Equipment and spare-parts shipping: reinforce suitable industrial cases and wooden crates.
Best fit: steel-strapping jobs that value portability and freedom from external power. For continuous, high-volume packing, compare operator effort and cycle time with a powered system. Round or irregular loads require an application-specific fit check.
Technical specifications
A333 manual sealless steel strapping tool
| Functions |
Tensioning, sealless joint formation and strap cutting |
| Strap material |
Steel strapping; not PP/PET plastic strap or metal cable ties |
| Width range |
12.7โ19 mm; nominal 1/2โ3/4 in. Correct width-specific setup required. |
| Factory setup |
Nominal 3/4-inch steel strap |
| Strap thickness |
0.38โ0.58 mm / approximately 0.015โ0.023 in. |
| Strap tensile strength |
700โ850 N/mmยฒ (MPa), as specified in the manual. Low-elongation strap is unsuitable. |
| Tool weight |
3.9 kg / approximately 8.6 lb |
| Power source |
Manual; no electricity or compressed air required |
| Joint efficiency |
Manual-stated approximate value: 80% of strap tensile strength. Not a load rating; results depend on strap, setup, tool condition and operation. |
Inch sizes are nominal where indicated. 12.7 mm and 13 mm are not identical; match the actual strap dimensions to the tool setup.
Understand the workflow before you buy
Wrap and load โ tension โ form the joint and cut โ release and inspect. The integrated mechanism keeps these stages within one tool. This overview does not replace the operating manual or operator training.
Check the joint, not just how tight the strap feels
-
Correct joint: the interlocking cuts are properly formed, the upper strap is cut cleanly and the lower strap is undamaged.
-
Too shallow: incomplete joint formation or an uncut upper strap requires correction before use.
-
Too deep: a scored or damaged lower strap is unacceptable even if the joint feels tight.
Do not handle or ship loads with defective joints. Follow the manual for inspection, adjustment and maintenance. Wear protective gloves and safety glasses with side shields, stand to one side of the strap, keep bystanders clear and use edge protectors on sharp corners. Never use strapping to lift or pull a load.
A333 questions, answered
Do I need separate metal seals?
No. The A333 forms an interlocking joint in the steel strap itself. You still need compatible steel strapping and the correct tool setup.
Does it need a compressor, battery or power outlet?
No. Tensioning and joint formation are manually operated. Operator effort varies with the strap and application.
Can I use my existing steel strap?
Check all four factors: actual width, thickness, tensile strength and elongation suitability. The listed thickness is 0.38โ0.58 mm. The current tool is factory-set for nominal 3/4-inch strap; contact us before ordering for other widths or uncertain steel grades.
Is the selected A333 option a complete tool or a spare blade?
The A333 option on this page is the complete manual strapping tool, not an A22 replacement shear blade. Contact us to confirm any additional accessories or consumables needed for your application.
Can it strap every package shape?
The tool needs a suitable flat surface for placement and operation. Check round, small or irregular packages with us before buying. Package strength, edge protection and your load-securing requirements must also be considered.
How do I request maintenance or replacement-part help?
Email your tool model, order information, a photo of the issue and the manual's part number. Relevant references include the A14 tensioning wheel, A15 gripper and A22 shear blade. We will check compatibility and availability; do not assume parts from other A333-branded tools interchange.
