It's a sad fact that most modelers' "bolt bins" consist of a small container with various nuts, screws, and washers from recently re-kitted aircraft. I'll be the first to say that I amassed a hefty supply of bolts over the years; I was proud of my collection and if you gave me 10 minutes, I could probably find the correct screw for the job, or at least get close. But after discovering the RTL Fasteners' Master Builder Assortment, I've already put those long fastener-hunting safaris behind me.

In this review we'll take a look at RTL Fasteners' Master Builder Assortment, a kit containing 2,124 pieces of hobby-appropriate hardware. We'll also look at their Miniature Wood Screw Assortment, and their new Bonded Washers (both available separately).

Overview

RTL Fasteners has included in the Master Builder Assortment a sampling of the most common types of fasteners used in the radio controlled hobby. Whether you're a fixed wing afficionado or you prefer the company of hovering aircraft, this kit won't discriminate. Even the surface crowd (vehicles and boats) will benefit from the diverse assortment of nuts, bolts, and screws found within.

The assortment comes unassembled, with all fasteners individually packaged and labeled by type. The easiest way to assemble the kit is to cut out the included diagrams and tape them to the inside of the plastic cases, then fill the compartments accordingly; we'll cover that in the assembly section below. Lets take a look at everything that's included.

Available separately from the Master Builder Assortment, the Miniature Wood Screw Assortment contains 350 brass pan Phillips wood screws and an organizer. This assortment has all the hard to find small screws you'll need for almost any job. The Miniature Wood Screw Assortment consists of:

Bonded Washers - Available Separately

The bonded washers feature a steel washer with a neoprene rubber backing. These little guys provide some vibration dampening and are great for engine mounts and plastic or fiberglass canopies. They also act as lock washers, preventing screws from vibrating out. The come in #4, #6, #8, and #10 sizes.

Assembling the Master Builder Assortment

The assortment is easy to put together, but does take some time; there's alot of hardware to sort through. Start by cutting out each one of the four printed diagrams and taping them to the inside lid of each container. Next, cut apart the plastic dividers that make up the separate compartments. Place the dividers according to the diagrams and fill each compartment with it's respective hardware. If you fill the compartment with the wrong hardware (it can happen after 30 minutes of reading labels and looking for bags) then just use the included magnetic pick-up tool to remove it... assuming it's not aluminum or brass.

Conclusion

The Master Builder Assortment is a must have for any modeler. Whether you're into cars, boats, helis, or airplanes, this diverse assortment of fasteners will keep you out of the hardware store and on the field where you belong. Speaking of the field, the locking cases are perfect for bringing along with you, without worrying about spilling anything.

If you're on the fence about spending money on boxes of nuts and bolts, just think about all the time you've spent sifting through your collection of hardware only to not find what you needed. Or the times you've used the wrong size and "made it fit." Do yourself and your model a favor; make the investment in a quality hardware collection that will last for years.

Pluses

  • The kit contains a great collection of commonly used hardware in our hobby.
  • Locking containers wont spill, especially when out in the field.

Minuses

  • Not enough blind nuts included when compared to the other hardware quantities; I would like to see more thrown in.

I could see these finding a home in my trailer! There always seems to be someone looking for some hardware whenever I'm out at the field.

Value is subjective. I personally think its worth it to have almost every fastener you would need for building or repairs, labeled and easily accessible, that will last you for years (assuming you arent running an aircraft building service).

Nice review. Pricey though.

A great alternative is Trimcraft Aviation RC. They have stainless steel fasteners in metric and standard SAE sizes. Lots of other things too. The quality of the fasteners is amazing for the price. For example, twenty-five (25) 4-40 x 3/4" stainless steel socket head are only 50 cents! Their shipping is only $2.99 in the USA for any size order.

Check them out. I have purchased just about every socket head (my favorite) fastener they have. I now have a fantastic variety of hard-to-find 2mm and 2-56 sizes, as well as all the larger sizes, washers, blind-nuts, wow. It is terrific to have almost every size on hand. I am not affiliated with Trimcraft, I am just a very satisfied customer, and I wanted to pass on this info to others in the hobby.

Service is fast, and Gino is very helpful and responds to emails quickly.

Check it out!

So I saw this item at the hobby shop, bigger than a brick and must have weighed ten pounds! The price gave me a little sticker shock at first, but after seeing how much is included in the kit I think it is worth it for the avid RC builder. If you consider how many tiny 2 buck packages it would take to comprise what is in the box it is actually a good deal. You'll probably become a popular guy at the field too when someone needs a piece

Now thats good thinking... helping out the guys at the field... the price (for me) has been justified...

I order from RTL as I need them. About 50% of the master builder assortment is too short, etc.

I bought this assortment last year and it's worked out well so far. Could use some more Phillips head screws,but the hex drive is really better as you get no cam outs.

Years ago, When the babies were babies, I started washing out the little jars and keeping hardware in them.
And then I found a 3 drawer, metal box... each drawer held 24 jars!

As I build a model, or touch up finished models (changing servos, or power systems), all the unused hardware or left overs go into a small margarine tub. Every now and then, I spend 20 minutes sorting out the bits and putting them into their proper jars.

When I notice I am running low on an item, I take the time to check all the jars, put together a list, and order what I need.

The items in my collection very much parallel what the "set" has.

never thought I would read an entire review on hardware LOL. This sure would make my life easier; I tend to have 3-4 projects going on at a time and there are always bits of hardware that halt my progress to go to the LHS...very nice.

I particularly like those rubber backed washers; perfect for cowls.
