4 Pack Quick Release Pin, Diameter 1/4"(6.3mm), Overall Length 3.75"(95mm), Usable Length 3"(76mm), Full 316 Stainless Steel, Bimini Top Pin, Marine Hardware

I received a stationary bike, but the pull knob was gone, which means the seat slid down every time I got on it. So I ordered these pins as a quick fix, and they do the job perfectly! I am 225 lbs, and the bike seat didn't move an inch once I placed the pin. Very sturdy and durable!

Great price, and they work great for speaker and lighting stands. Cheap enough to toss a bunch in the stage boxes. I'll buy more.

These are exactly what I needed for umbrella pin replacements. They fit perfectly and feel solid.

I’ll set the stage. I live in an HOA community in Florida. I’m a HAM radio operator. Antennas are mounted on a telescoping flag pole. Thunder storms in Florida are very frequent and I have to raise and lower the antenna mast pretty often in the summer. The twist-lock feature of the telescoping pole becomes difficult to work with over time due to moisture and dirt. So I stripped all those locking mechanisms from the pole and drilled holes in various places depending on the height I wanted. These pins work perfect when inserted in the hole and makes raising and lowering super easy and fast. The pins just hang on a quick release key ring by the mast so they're out in the weather 24/7 and have held up incredibly well. Simple solution to my frustrating problem.

Good quality and fit. Used to keep bed up in the Motorhome.

I use these for my saltwater fighting belts, so I have a quick release if needed during a fish fight. I drill a 1/4-inch holes across the cup and place 1 of these all the way through the other side of the cup. If your rod has a castled butt, use the bar in place, but if your rod has a smooth butt, remove the pin. Fight the fish and enjoy fresh fish for dinner.

I recently bought a previously owned toy hauler camper that was missing the "pins" to hold the upper bunk in place. These pins are a perfect replacement for this use.

Slightly modified the pins by removing the ball stop drilled it thru and rounded the point, used a cotter ring on that end. Anyway it works great on my 1985 O'day Daysailer mast hinge point, Perfect! Thanks.

They are pins, they fit the hole, and the are doing their function. They have not snapped or corroded. Due to having stops at both ends they have not fallen out. I have not put them to extreme test, so I can not comment on whether they are an outstanding product, or merely average.
