Big Horn 19709B-5PK 5 Star Thru Knob 3/8 x 16 (5/PK)

The threads in these knobs seem to be the smoothest operating threads I've ever felt in a star style knob. Thread it on to the bolt/stud and spin it ONCE and it essentially threads itself all the way on to the bolt. Much smoother than the threads in a HiLift locking knob or any of the similar 3/8-16 knobs I've got. Smoother than a hex nut or wing nut. I use this gizmo as the "second" nut on a HiLift, axe/shovel, or other pioneer tool mount. One locking, one like this. Works great. Doesn't seize. Arizona UV doesn't even seem to degrade it as much as some plastics.Thanks - Lumpy

Secured a 1.25" modified steel square tube to my truck bed. Drilled another hole up by the tie-down hole above the wheelwell and inserted a bolt from the inside. Using this product and a couple washers I was able to secure my harbor freight floor jack to the bed wall right on top of the wheelwell. A mounting bracket is a couple hundred, my 10 dollar fix works well, giving me easy access and out of the way storage for my exhorbently overweight floor jack.

Hard to find product. Work as described. Using 4 knobs to hold a set of x-Bull traction boards to a Thule roof bar system on a Jeep with a custom bracket. 250 mile round trip including off-road abuse and they did not loosen at all. Good stuff.

I bought these to replace the original cracked/broken wheel locks on my 17 year old Murray mower. They thread on fine but because of the extended shoulder, they protrude from the wheel too far and they constantly catch on fences lattice or anything I get close to. Looks like I bought them for the wrong application. Besides that they thread on to anything that requires a 3/8" - 16 nut.

Big Horn 19709B-5PK 5 Star Thru Knob 3/8 x 16I've used 10 of these knobs on various projects. They are outstanding. Well constructed, well designed with a brass threaded insert, and easy to grip for tightening.I also “converted” two Big Horn knobs to "clamping knobs" by screwing in 2" long 3/8" x 16 stainless steel socket head cap screws into the knob (and tightening with an Allen wrench), as shown in the Customer Image.

Built an art easel for my daughter-in-law and used these for the slides to adjust the tilt. Worked great and good quality.

I have used several others of this type. These are WAY better. Slightly larger, better impregnated threads, doesn't feel like it is going to break when tightening. I painted one red and use them for my batteries. Perfect thread insert because it slightly sticks out on the flat end...for better electrical contact.

I bought these to mount an after-market storage box to the back of my UTV (side-by-side). They look great and work perfectly to keep the box secure while allowing easy removal when you need to take it out.

Everything perfect

gave my grinder idler a much needed adjustability

Worked as required. Threafs a but loose, but not enough to effect the use for tensioning wood working jigs. Good finish, good value for the money.

Very high quality, very smooth threads. Used to install swivel fishing chair on my kayak, makes it easy to keep hardware snug with no tools.

More than what I wanted to pay but they do the job.
