Worth it for contractors installing 3/4-inch solid hardwood flooring who need the mechanical bond that L-cleats provide. The L-shaped head allows more natural wood expansion and contraction compared to rigid staples, reducing tongue splitting. At 4.7 to 4.9 stars across 500+ reviews, these nails deliver what flooring pros actually need — fewer jams and solid hold.
Skip it if you’re running staples successfully on stable engineered flooring. Staples give higher immediate holding power in materials that won’t move much. This kit shines with solid hardwoods that expand and contract with Montana’s seasonal humidity swings.
The L-Cleat Advantage
The L-shaped cleat design creates a mechanical bond that moves with the wood instead of fighting it. Montana’s dry winters and humid springs put serious stress on hardwood floors. Unlike staples that lock rigidly in place, cleats allow controlled movement while maintaining hold.
The coated finish does double duty — reduces friction going in and increases pullout resistance once seated. The adhesive collation keeps strips feeding smoothly through the nailer. No fumbling with loose nails or dealing with separated strips.

Reviews consistently mention reliability — “very few jams” and “floors feel solid without squeaks.” That’s what matters when you’re 800 square feet into a job.
Tool Compatibility That Actually Matters
These cleats work with Bostitch’s own MIIIFN and MFN series, but also run through NuMax SFL618, Freeman PFL618BR, and Dewalt DWFP12569. Reviews specifically call out smooth operation in budget-friendly NuMax nailers. You don’t need the premium nailer to get premium results.
Space cleats 6-8 inches along each board. At that spacing, a 1,000-count box covers roughly 200 square feet — enough for a decent-sized bedroom or small living room. The 2-inch length handles standard 3/4-inch solid hardwood, including tougher species like Brazilian Cherry and Hickory.
Installation follows standard practice: load the strip, adjust your nailer’s base plate to match the flooring thickness, and test fire into scrap to verify the nail seats flush in the tongue pocket. Nothing revolutionary, but the adhesive collation and consistent quality mean fewer interruptions.
The Professional Verdict
Bostitch FLN-200 has earned its reputation as an industry standard — priced higher than generics but with fewer reported jams. The L-cleat design matches specific nailer configurations (different from T-cleats that use T-shaped heads for other tool models).
The main complaint? Occasional shipping damage where strips arrive broken. Still usable, but annoying. Some retailers charge significantly more than online sources — worth shopping around if you’re buying multiple boxes.
Coverage follows standard retailer return policies. Bostitch focuses warranty support on their tools rather than consumables. Not surprising for a fastener product.
Frequently Asked Questions
Q: Will these work in my older Bostitch flooring nailer? A: Compatible with MIIIFN, MFN-200, MFN-201, MFN200-S, and MIIIFS (with adapter). Check your model number against this list.
Q: What’s the real difference between L-cleats and staples for hardwood floors? A: L-cleats allow natural wood movement through their mechanical bond design, while staples lock rigidly in place. Cleats reduce tongue splitting but staples offer higher immediate holding power. Choose based on your flooring type and local humidity swings.
Q: How many boxes do I need for a typical job? A: At 6-8 inch spacing between cleats and 1,000 nails per box, figure roughly 200 square feet per box. Always buy extra — running out mid-job costs more in time than a spare box costs in money.
Q: Can I use these with bamboo or engineered flooring? A: The specs list compatibility with engineered hardwood (verify thickness), bamboo, and exotic hardwoods. But these are specifically designed for 3/4-inch solid hardwood. Check your flooring manufacturer’s fastener requirements.
