A Clean, Crafted Finish for Outdoor Builds

The rounded carriage head delivers a neat, unobtrusive accent that lets the wood grain take center stage. I love the tactile, chalky sheen of hot-dipped galvanization—it feels honest and architectural. Use them in rhythmic rows along a fence or garden gate for subtle texture and cohesion. It’s the kind of quiet hardware that elevates everyday structures into refined, lasting design.

Choose these galvanized carriage bolts for a clean look and rust-proof strength on your next outdoor build.

Good keyboard, some auxiliary keys are moved from where I was used to
I've only been using this for a day, so I can't speak about battery life. It is rechargeable, and it has an on-off switch for saving the battery when I'm not using it, so I don't know what more I could ask for on that front. Likes: the main keyboard is definitely ergonomic and feels comfortable; the key action is not silent, which I actually like, and the scissor action switches underneath the keys feels good to me; the keyboard is about 1.5" narrower than my previous keyboard (Logitech Ergo K860) because the number pad is right next to the regular part of the keyboard, and the usual keys in between have been rearranged. Most of these changes will just require the user to get used to the new positions. However, the Home, End, Pgup and Pgdn keys are now Function keys, piggybacking on the arrow keys, and that may cause more trouble for people who use those a lot (I don't, so I don't mind it). Dislikes: experience has shown me that dust and crud get into the space between the wrist pad and the rest of the keyboard. On my old keyboard, I could remove the wrist pad using some tiny screws in the back, and take the pad out for thorough cleaning. With this keyboard I won't be able to do that, so time will tell how aggravating that will be. Maybe I'll have to take it down to my shop and blow out the crud with the air compressor (joking, probably not a good idea). Overall, not quite 5 stars, but close. If it lasts better than the Logitech, I may come back and put in that last star. Update: It has lasted about 20 months, and I'm going to have to replace it. I may buy another one, 20 months is pretty good for the amount of use I have gotten out of it, but I'm going to search to see if anything new and better is around. Symptoms seem to indicate that the rechargeable battery is not taking a charge any more. The keyboard works find when it is plugged in, but when I unplug it, after a few minutes it goes wacky.

Arrived Battery DOA - But then something unexpected happened.
This was a one star review because the unit arrived with a batter that would not hold charge for more than a minute. I am not changing the stars, because if you are like me, you read the one star reviews cause so many companies pay for fake 4 and 5 star reviews. When I first posted this review I also initiated a return and just planned to move on to another brand. I was surprised when I got a personal email from the Arctek Service Team offering to send me a replacement free of charge. With nothing to lose I figured why not? The new unit arrived and I put a full charge on it and put it to work. I chose this keyboard because it is the closest in layout to the original Microsoft ergo split keyboard, no longer in production, that I have used for years and truly enjoy. I am pleased to report that the battery is working fine and the keyboard performs flawlessly. No skipped strokes or stuck keys, no glitches with the proprietary wireless interface to the laptop (when I am using it on the desk with a large screen). My hat is off to the Arctek service team and management. A company that cares enough about its reputation and customers to go to so much effort to take care of a customer with such a small dollar item sale is a company you can expect to rely on. From now on when I want electronic gear on Amazon, I am going to use the word Arctek in my search.

Incredible
1 year update: I have been using this keyboard daily at work for almost one year and my 5 star review stands. Upon receiving the keyboard I charged it before use, and since then I have not charged it at all and it is still somehow at 75% battery!! I turn it off at night when I’m done. One of the function keys broke off in a way where I can’t reattach it, but I reached out to customer support and they sent me a free replacement keyboard. Great customer service and warranty! Original review: I love this keyboard. I am a grant writer so I write and edit all day. It has really leveled up my typing experience and has made work much more comfortable. It puts my hands in a natural position so my wrists no longer bend at odd angles. I adapted to the split key design in minutes. The keys have an excellent feel and sound to them and the wrist pad feels like a soft cloud. I’ve had no connectivity issues and so far the battery has been stellar. It also has rubber grippers on the bottom so it stays firmly in place on my desk and doesn’t move around like my old keyboard did. I went for this one because I didn’t want to spend $100+ on a keyboard and I’m really impressed with the quality.

OK, but .....
It is an ok keyboard with an annoying flaw. As other reviewers have observed, the placement of the Number Lock key makes it easy to trip that key by error. it is distracting to have to break your train of thought to fix the problem.

Great value for quality design
Super sturdy and sleek. It is exactly what I needed. It is small enough to move around when I move my laptop. I use it on a slide out from my desk so that I can work while I watch TV. It also keeps my laptop cool with airflow on all sides. It couldn't be simpler.
