This fitted, hinged plastic box from American Tool Group would be worth buying even if it didnt come with hundreds of O-rings. And it does. Black nitrile O-rings sorted by size. O-rings that will stay in their places until you need them. The 407-piece set includes 32 sizes from 1/4" OD x 1/8" ID x 1/16" to 2-1/4" OD x 2" ID x 1/8". It includes the size you're going to need. At your fingertips. Instead of in aisle 12 at the home center.

Wallace’s pooches before Gromit came along? Nope, just a handy 2-3/8" long x 3/8” ID steel snap hook attached to a 13/16” ID ring that swivels 360 degrees. In some fashion circles, hanging your keys from a belt loop of your jeans with one of these is considered mandatory.

That’s a seldom-heard auto and woodshop taunt. Also true of this, our largest ratcheting long-nose plier clamp. Measures 9-1/2” long with 3-3/4” long serrated jaws that have pivoting end pads. Opens to a yawning 3-1/8” and has a quick-release trigger.

Hemostats are the clamplike devices dangling from veins and arteries in melodramatic operating scenes. Our particular collection are Pakistani surgical-grade instruments made of magnetic stainless steel. As such we rate them pretty good, but not fantastic. Hemostats look like little pliers. The jaws are relatively fine, with rounded tips. The inside faces are lightly serrated to get a grip on tubing or body plumbing. And the handles are much longer than the jaws. Now the heavenly part. Great hobby clamps that can be worked into small areas. Fine heat sinks for electronics. Good hook extractors for trout fisherpeople. Excellent tubing clamps for flow-sensitive chemistry experiments. Sizes are approximate length.

You’ll get a great big bunch of hooks, including cup hooks and gate hooks, plus assorted eyes in assorted sizes and finishes--steel, brass, white. It’s a gallimaufry of hardware and it’ll save you years of trips to the hardware store because you’ll have the stuff you need already on-hand, barely taking up any space. You’ll get an assortment of (5) packs in, yes, assorted sizes.

Like a third hand in the electronics lab, this circuit-board rack from Elenco® has a pair of stable 6-1/2" legs and 3" tall arms with clips, one spring-loaded, to hold the board. It's a must for any electronics DIY-er. Adjusts from 0 to 9-3/8" apart and lets you rotate the board it holds a full 360 degrees. Both clips and legs lock with thumbscrews.

No, not Beverly Hillbillies, just super-handy small plastic spring-loaded clamps, 3-1/2" long with 2" padded jaws. We'll pick (4) from our array of neon colors, but you can call them Jed, Granny, Elly May and Jethro if you want.

These are the gold standard of twist ties, not to be confused with those skinny little suckers that come on all electronic cords in the known universe. These are Gear Ties®, coated in protective, grippy black rubber with heavy rubber tips, 3" long x 1/8" dia (they look sort of like boot laces with match heads on the ends), suitable for indoors or outdoors, reusable veritably ad infinitum, and oh so satisfying to twist and creatively crimp. Use them for bread bags, earbuds, napkin and silverware sets, power cords, USB cables, mic cords or garden hoses--or turn them into jewelry and be the most interesting person at the party. You pick: the (4)-pack of 3” long ties; or the (2)-pack of 12” long ties.

These gray foam washers/spacers/vibration pads are 1" OD x 1/2" ID x 1/4" thick with a peel-and-stick self-adhesive face on one side. They'll make your doors and drawers land more softly when you close them. Also useful as non-scratch and non-slide feet.

If so, you don’t have to bend paper clips to hang stuff from them. You could just buy a bunch of these 2" white plastic ring thingies that twist onto the 1” tracks that hold most ceiling tiles. A 1-3/8” dia tab with a 7/8” dia hole sits perpendicular to the ceiling, ready for whatever you want to suspend from it.

This simple, clean-lined chromed cabinet latch will tell every visitor to your home that you're standing right at the cutting edge of elegant home design. Each latch is 3/4" x 1-3/8" long with a 1-3/8" x 5/8" plate and a 1-1/4" long handle centered on a tasteful dome. Includes a mounting nut. Made in the USA.

Big sack o' springs. You get (10) springs, mostly compression but probably with a few extension springs thrown in for dessert. Great for art projects, kinetic sculpture or creating tension in any number of scenarios. In sizes ranging from 3/4" long x 1/2" dia up to 2-5/8" long x 1-7/8" dia.

Devices used to hold spring in place, thus ensuring eternally promis-ing, but changeable and wet weather. No? How about this then: Steel grips, spring loaded to keep their tips tightly closed on whatever you chose to target. The handles and tips have been coated with a light plastic to improve grip and provide a bit of insulation. The clamp is about 4" long x 5/8" wide and opens about 1-1/4". They have strong grips and will crush fragile items, but do a good job of holding things while the glue dries, you do the soldering, or the materials bond.

Clamps. Whatever. These measure approx 5" long x 1-1/2"' at their widest. They open to about 2", though, so they'll not only grab test tubes, they'll pluck cubes from an ice bucket. Or carry a few stems of asparagus. And you do get a pair, so you could always have a tong war.

This double burette clamp has rubber-coated jaws that can grip a cylinder up to 1-1/2" dia. The adjustable jaws swing on a T-shaped lab-stand clamp for free horizontal movement. Not a chemist? These are perfect for metal sculptors creating fanciful crabs, lobsters and crayfish.

These standard pegboard hooks fit, wait for it, standard pegboards, with 1” spacing on the legs, and made of 7/32” steel. Not really hooks, these are the long straight thingies with a slight upward angle to approx the last 3/4”. You pick the 3-1/2” long or the 5-1/2” long ones. Very handy in pantries, basements and garages. And isn't it time you finished that organizing project from last year? 

Brass L-shaped shoulder hooks (Why aren’t they elbow hooks?) are handy to have around. Each has a thread about half as long as the hook itself, and a small plate that fits against the wall. You get (2) packages, for a total of (6) 1” hooks, or (4) 1–1/2” hooks.

O my. It's time to restock the O-ring cabinet. You'll get (36) total, (6) bags of (6) black rubber O-rings, all 1/8" thick. Each bag will have (2) 1-3/4" OD x 1-1/4" ID and (4) 3/4"OD x 1/2" ID. Made in the USA.
