BIG HORN 15111 Magnetic Cap Nail Roofing Hammer
This one-handed nail placement hammer uses a magnetic head to secure plastic and metal cap nails, enabling fast driving while keeping fingers away from the fasteners. A built-in rip claw on the opposite side helps with quick nail removal and material adjustments, making on-site tuning simple and efficient for roofing, wrap, and dry-in work.

It is noted for a lightweight design at 4.8 lb and ergonomic handling, suited for roofing felt, foam insulation, and house wrap. The tool’s Pro-Preferred reputation reflects consistent performance in professional settings over many years.
STINGER CH38-2 Cap Staple Hammer Tacker
This lightweight unit weighs about 2.6 lb and enables delivering a cap and staple in a single step. It’s designed for straightforward application on roofing underlayment, house wrap, and insulation projects, promoting best-practice installation with fewer tool movements and increased accuracy.
STINGER NailPac Cap Nails
The NailPac combination provides 1″ stainless-cap nails with 1″ plastic caps compatible with CN100B. It emphasizes quick reloads and safe, efficient placement, making it a preferred pairing for scenarios where both caps and nails must be loaded concurrently for faster throughput on roofing projects.
One Stop Outdoor 250 Pack Plastic Cap Nails
This set pairs round 1″ plastic caps with galvanized tar paper nails, designed for secure fastening of roofing felt, house wrap, foam board, and insulation film. The corrosion-resistant nails extend service life, while the flexible cap head aids water resistance around the cap edges.
One Stop Outdoor 500 Pack Plastic Cap Nails
This larger set mirrors the 250-pack design with 1″ caps and galvanized nails, offering extended supply for bigger projects. The round cap design remains aimed at minimizing water intrusion and simplifying the installation workflow, especially on extended roofing or wrap installations.
One Stop Outdoor 250 Pack Cap Nails (Alternate)
This listing offers another 250-pack option with the same quality design motif: reliable plastic caps, galvanized nails, and a round cap head to help prevent water ingress. It provides an alternate purchasing route while maintaining compatibility with CN100B and similar nailers.
Buying Guide: Key Purchase Considerations
- Tool type and firing mode: Pneumatic cap nailers and cap staplers come with bumpfire and sequential options. For high-volume installs, bumpfire can boost speed, while sequential mode helps with precision in tight spaces.
- Weight and ergonomics: Lighter tools reduce user fatigue on long days. Ergonomic handles and balanced weight improve control when working on roofs or against walls.
- Compatibility and reloads: Confirm nail and cap compatibility and the reload capacity. Tools that hold caps and nails in equal numbers minimize reload frequency on busy jobsites.
- Depth of drive and exhaust: Tool-free depth adjustment allows for consistent cap seating. A tool-free exhaust system helps direct air away from the operator, increasing comfort and safety.
- Durability and materials: Stainless or galvanized components resist corrosion in outdoor conditions, extending life in harsh weather or salt-exposed environments.
- Applications: Choose based on whether you’re mainly installing roofing felt, underlayment, house wrap, or foam insulation. Some tools are optimized for multi-material tasks with compatible nails and caps.
- Maintenance and support: Look for tools with widely available replacement parts and reputable customer service to minimize downtime after field use.
- Cost of consumables: Consider the ongoing cost of caps and nails, and whether combined NailPac or similar bundles save time and money.
Overall, the selection should align with project scope, user preference for firing control, and durability in outdoor environments. For professional crews, a combination such as a CN100B-capable nailer paired with NailPac caps or compatible nails often yields the best balance of speed and reliability on roofing underlayment, house wrap, and felt applications.
