Two details need a version check: CN55’s published minimum nail length differs from the pictured nameplate. CN65B’s published head-diameter units disagree at the upper limit. The exact tool label or drawing resolves these fields.
Find a model to check
This table screens our standard coil sizes by metric nail length and shank diameter only. It is a starting shortlist. Head diameter, angle, wire position, nail pitch, coil diameter, magazine capacity and the supplied tool version must also match.

Ask for a dedicated tool check
Automated pallet lines: Jumbo coils typically hold 3,000 nails. Check the machine’s coil support and feed requirements separately from a handheld nailer magazine.
At the pallet workstation
Pallet assembly
Select the nailer around the joint, fastener specification and production timber.
Joint access and loading
Check nose access, handling and the loaded coil on the actual workstation.
Choose nails for your timber
Our standard and Jumbo coils offer Q195 and Q235. Q235 denotes a higher base-steel yield grade; wire processing and nail design also affect the finished nail. Compare the finished sample in your timber and tool.
Q195
Compare this option when trial nails drive cleanly and the completed joint meets the required holding performance. Select for the job and avoid unnecessary material cost.
Q235
A higher base-steel yield grade. Compare finished samples in your timber and nailer; the grade alone does not establish finished-nail strength or a pallet load rating.
Softer timber: check penetration and pull-out performance. Dense timber or knots: trial diameter, point, material and tool setup together. Green timber or repeated wetting: assess holding performance after moisture changes.
For different export markets, send the timber species, board thickness, moisture condition, pallet use and destination country. The timber and joint determine the selection.
Smooth
Lower driving resistance and a cost-focused option where the tested joint meets its holding requirements.
Ring
Compare for greater resistance to pull-out. Check the driving result in the actual timber and joint.
Screw
A deformed shank for additional grip. Compare with ring shank using your production timber and tool.
Ring and screw shanks normally require more driving energy than smooth shanks, especially in hard timber. For single-trip or repeated-use pallets, include handling cycles and the complete joint design in the trial; a shank profile alone does not establish load capacity.
Samples and ordering
Model & quantity
List the exact model and number of tools. Include your current coil sample and the fastener drawing for a joint tool-and-nail review.
Sample trial
Use representative production timber. Check loading, feeding and the completed joint before agreeing the order specification. Sample availability, minimum order and lead time are quoted for the selected tool.
Manuals & spare parts
Agree the supplied version, operating manual, air connection and spare-parts list. Keep the agreed sample, label and specification for repeat orders.
Practical use questions
Why does the nailer skip nails or jam?
Disconnect the air supply before inspection. Check the exact fastener dimensions, loading position and magazine height against the model manual. Remove a damaged coil and inspect the feed path, nose and driver for debris or wear. Persistent faults need service before production resumes.
What should I do if the coil wire is already broken?
Keep that coil out of the tool. Broken weld wires and a distorted coil can interrupt feeding. Retain the affected coil and carton label, then send photos of the break, packaging and tool model so handling damage and the batch can be reviewed.
What if nails bend or break during driving?
Stop and disconnect the air supply. Keep the damaged nails and batch label. Check for a specification mismatch, damaged driver or nose, and difficult timber conditions. Send the timber species, board thickness, tool model and clear photos; changing steel grade alone may not solve the cause.
Why are nail heads proud or driven too deep?
Check the depth setting where fitted and the regulated air supply. Trial the specified nail in your actual timber, using the lowest effective pressure within the exact tool manual’s limits. Do not exceed the rated pressure to force an unsuitable nail into the joint.
Can I use a Jumbo coil in one of these CN nailers?
A 3,000-nail Jumbo coil needs a machine and feed system designed for that coil format. A matching nail length does not establish magazine compatibility. Use the Jumbo guide for automated-line selection, or send the machine model and coil-support photograph for a feed-system check.
What should I send for a coil-and-nailer sample trial?
Send the tool’s full brand and model, a nameplate photo, the current nail or carton label, and representative timber details. Include nail length, shank and head diameter, collation angle, wire position and coil dimensions. For the pallet, specify joint thickness and the expected handling conditions.
Follow the manual for your exact tool when loading, inspecting or clearing a jam. Keep the tool isolated from its air supply during inspection.
