SF9000 PVC Flexible Round End Caps Shelf Organizer Tip Caps Wire Thread Protector Cover (inner diamter 6.5mm), 1/4 inch round black vinyl end cap, cover rubber safety tip 0.25"

I use the 25mm size to protect barrel extensions during shipping, and after many thousands of shipments, I have never had a single one damaged in transit. That kind of track record speaks for itself. They’re inexpensive, install quickly, stay in place, and provide exactly the protection they’re supposed to. When you’re shipping precision-machined parts, preventing damage isn’t optional, and these have proven themselves over and over again. The plastic is durable enough to withstand the abuse of normal shipping and handling, yet easy to remove when the item reaches its destination. There isn’t much else to say. They do their job flawlessly, and they’ve saved me from countless potential headaches.

Finally found caps that fit 1/2" emt conduit. Why is it so hard? These fit perfectly. Could be thicker, but will do.

used to protect rod ends they do what there made for.

I used these to cover the tips of my mic cord for a speaker set up. They worked well.

The mid-2000 version of the Bertha storm panel bolt consisted of a 1/4-20 threaded screw, a hex head and a 1/4" lag bolt (see my photos). These came with a white vinyl cap to protect the threaded part only. After so many years in the Florida sun these caps became brittle and very difficult to remove. They also did not protect the hex head. So after many years near salt water these heads started to corrode. A good portion of my house is now dark grey and I did not want to see a bunch white caps sticking out all over the place. Therefore I chose to use the Jocon black 10mm caps to cover both the threads and the hex head. Although their 9mm cap provided a slightly tighter fit around the hex head, the 9 mm cap is too short for these bolts. The 10 mm caps aren't quite as tight but I haven't had any fall off even in direct sunlight and 90+ temperatures. I also froze a few in my freezer and they stayed put. The inside length up to the tip is about 0.78".

I bought these to cover exposed rebar around our loop loc cover around our pool and the sizes aren't consistent...it could be the rebar but some were very snug which I wanted and some are just to big ...

Nothing too exciting here. Price is right .. shipping is Prime. I got the 7mm to try on 5/18-18 threads, the thought being that 8mm might be too loose. The 7mm will go on OK .. pretty snug .. for sure they are not going to fall off. I'm going to cut a few shorter .. probably use a q-tip with some dish-soap for the "shorties" .. losing the inside lead-in chamfer of the full length as received. Cheers!

I think these are great. I bought a pack of 8mm caps to cover the ends of Hornady primer tubes which are supplied with the Hornady primer filler product. For some bizarre reason they come without an end, creating a risk of dumping the entire tube. Great solution for this problem and the 8mm size fits on easily and with enough resistance that there is little risk of dumping while not so great that its tough to remove. I modified several of my original Hornady primer pickup tubes to add to the two that come with the filler, works great there as well.
