APPLICATION EXAMPLES
Where it's used
Explore the materials, joints and workshop tasks below. Match the fastener size and tool to your own workpiece before ordering.
Furniture panel-to-frame work
Compare the 8.82 mm crown with the available panel fixing area and required tool geometry.
Light wooden case panels
Trial panel attachment on the actual case substrate and intended handling duty.
Supported batten components
Check seating and edge condition where a two-leg medium-wire fastening is specified.

9240 Series 18 Gauge Industrial Staples: check the entire cross-section
A familiar series number helps identify a starting point. The crown width, wire width, wire thickness and leg length determine whether a candidate staple matches the tool and joint.
1. Record the crown width and confirm the supplier’s measurement convention on the order drawing.
2. Record both dimensions of the wire cross-section; gauge alone is insufficient.
3. Choose a listed leg length for the material stack and required penetration.
4. Compare the dimensions with the exact stapler model and approve a sample.
Choose for your workpiece and equipment
01
Identify the wider medium-wire crown
The reference is 18GA with 1.26 × 1.0 mm wire and 15–40 mm legs. Its crown differs from the 6.0 mm 9040 family.
02
Choose length for the joint
Allow for the attached component before assessing penetration into the receiving member. Check for point projection and splitting on production material.
03
Validate the complete tool range
A tool in the same series may accept only part of the available leg range. Compare the exact tool manual before approving each ordered length.
Questions before you order
Is 9240 simply a longer 9040 staple?
No. The crown geometry differs, so the magazine and driver requirements can differ even when wire gauge is the same.
What should a cabinet sample prove?
Agree the relevant seating, breakthrough, splitting and retention checks with the component designer, including any contribution the back panel makes to the finished cabinet.
Application limits to check
- Do not interchange 9240 and 9040 on gauge alone.
- Do not present a general packaging application as a certified pallet or structural connection.
