Frequently Asked Questions
Are these kits suitable for composite decking?
Kits with stainless or coated fasteners and appropriate thread types work on composite decking; the wire rope kit is useful for cable railing, while the Rockwill kit secures posts to concrete near composite deck boards. Always choose screws rated for composite or use manufacturer-recommended fasteners to avoid splitting or pulling out.
Will the stainless parts resist rust near pools or salt air?
304 stainless parts offer good corrosion resistance for most outdoor uses. For harsh salt-air environments, 316 stainless is better, but 304 is still a solid value under $20 and outperforms plain zinc-plated hardware.
Do I need special tools to use the wire rope kit?
You’ll need a proper crimping tool for secure sleeves and cutters for clean cable ends. Some users report the kit contains everything but the dedicated crimper if you plan repeated or load-bearing crimps; casual jobs can sometimes be done with pliers, but use the right tool for safety.
