OWT Hex Cap Nuts are the small detail that makes wood structures look custom-built. After you drive your OWT fastener, thread on the cap and seat the included plug to hide the hardware and discourage tampering. Use 1-1/2″ caps with OWT Timber Screws on plates, bases, and truss accents; use 1″ caps when you’re covering #8 self-drilling screws on lighter trim or accessory pieces. The durable, powder-coated aluminum construction is made for exterior projects and blends seamlessly with the rest of the OWT line.
Why Choose This
- Refined aesthetics — Hides fastener heads so the connection hardware doesn’t distract from your build
- Helps deter tampering — Finished cap and plug make casual removal less likely
- Part of a system — Sized to work with OWT Timber Screws and the broader OWT connector family

Installation
Lay out and mount your OWT connector. Drive the appropriate fastener (e.g., OWT Timber Screw with a 3/8″ hex driver). Thread the hex cap onto the fastener until seated, then press the plug into the cap recess to finish. Re-check alignment and tighten hardware as needed. For disassembly, remove the plug and unthread the cap.
Buying Guide
- Pick your size: Use 1-1/2″ caps with OWT Timber Screws on structural connections; use 1″ caps to conceal #8 screws on lighter accessories and trim.
- Match the system: These caps are cosmetic; choose fastener length and connector sizing per your OWT bracket or base.
- Suggested complements: OWT Timber Screws and OWT Timber Bolts for through-bolt looks without exposed threads.
Frequently Asked Questions
- Do these include the screws?
- No. The caps and plugs are included; select your OWT fasteners separately to match the connector and load.
- Are the caps weather resistant?
- Yes. They’re powder-coated aluminum designed for outdoor service when installed per OWT instructions.
- Can I remove a cap later?
- Yes. Pop out the plug and unthread the cap to access the fastener head.
- Which size should I use?
- Use 1-1/2″ with OWT Timber Screws on plates and bases; use 1″ for covering #8 screws on lighter accessories.
Comparison
- Hex Cap Nut (this item): Flat-faced aesthetic; pairs cleanly with OWT Timber Screws and most OWT connectors.
- Hammered Dome Cap Nut: Same concealment with a rounded, hammered style for a more rustic look.
- No cap used: Fastest/cheapest, but leaves screw heads exposed and easier to tamper with.
