HARDWARE
We have tools and hardware including standard, flathead, and buttonhead bolts in alloy or stainless steel, t-nuts, screws, drill bits, and wrenches!
Our "Hardware recommended" section of each product page says the bolt size that will work for most walls with t-nuts from flush to a "normal" recession of 1/4-1/2". If your t-nuts are more recessed (the start of the t-nut barrel is 3/4" or more from the surface of the wall) let us know so we can make sure you're getting the right length bolts!
We endeavor to include a proper attachment method to all holds that are purchased with hardware included, but unusual walls or deep t-nuts can require longer-than-normal bolts and also mistakes can happen in packaging and occasionally the wrong length bolt/screws will be sent. You are responsible for understanding what a correct attachment is and if we have sent you the wrong thing by accident we are very sorry and will replace it with the correct size but we are not responsible for you incorrectly attaching your hold even if it's with hardware we provided. Seek professional help to make sure your attachment points are correct!
BOLTS
All climbing holds bolts are listed in standard (not metric) and assume a t-nut depth of 1/4"-1/2" from wall surface. Bolts come in alloy (black, normal climbing hold bolts) or, if requested, stainless steel (for outdoors/wet environments, slight upcharge). Bolts are 3/8" x 16 thread.
We have Standard (aka socket head cap screws, which are the most commonly used bolts in climbing holds and take a "big" 5/16" wrench), Flathead/Martini (look like a martini glass when held sideways and take a "small" 7/32" wrench) and Buttonhead (small domed head, good for low profile footholds with the washer close to the hold's surface, take a 7/32" wrench)
Standard Bolts: Standard 1.5" bolts are fully threaded. Standard 2" and longer will have an unthreaded neck section between the threads and the head. Buttonhead and Martini/Flathead thread lengths/neck sizes will vary, email us if questions.
Styles of Bolts: If your holds are tiny footholds with the washer close to the surface you'll need Buttonhead Bolts, or if they have no washer and instead have a countersunk attachment point (looks like a martini glass would fit in it) then the bolts have a flat top and are called Martini Bolts / Flatheads and we have those as well.
Standard vs Metric: Standard 3/8" bolts are what we use in the US, Metric M10 bolts and t-nuts are used in the UK and Europe. M10 is slightly larger than 3/8". 3/8" bolts will actually work in M10 t-nuts, but because the Standard 3/8" bolt shaft is a little smaller than a Metric M10 bolt shaft, a Standard bolt in a Metric t-nut is a bit more likely to strip out the threads. Metric M10 bolts DO NOT fit in Standard T-Nuts, or sometimes you can get them in but they'll usually get stuck. It's always recommended to make sure you have the correct hardware that fits together correctly.
Most bolt sizes are recommended on each set page and calculated for you in the cart. If not or if you have specific questions, please email us and we will help.
SCREWS
If you choose the hardware option for jibs or with Treadwall Packs or a Kilter Board, you will receive screws with your order. The screws up to 2" are 8 gague T-20 (torx head) self tapping wood screws. 3.5" and longer will be T-25 torx. These are the same or very similar to screws commonly used in setting and can also be found at hardware stores.
T-NUTS
We have zinc and stainless pound-in t-nuts and zinc screw-in (3-screw) t-nuts available. These t-nuts work well if you drill your holes with a 7/16" drill bit or paddle bit.
We also have industrial zinc t-nuts from Magic Lab in Canada. These take 3-screws (not included) and are thicker than the other t-nuts. The barrel is 1/2" long and a 17/32 bit is recommended to drill holes for them, or 9/16" will work.
TOOLS
We have hand wrenches, impact-end 5/16th bits (regular setting hex bit), 7/32nds (martini/flathead/buttonhead bolt size), both in a kit, and impact-end T-20 bits available.
