Simpson Anchors SDS25312 Description

The Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screw is a 1/4"-diameter high-strength structural screw ideal for various connector installations as well as wood-to-wood and engineered wood applications. It installs with no predrilling and has been extensively tested in various applications. The SDS is improved with an easy-driving Type-17 point and a corrosion-resistant double-barrier coating. The SDS Strong-Drive 1/4" wood screw line has expanded to include stainless-steel SDS screws in 1 1/2" to 3 1/2" lengths, suitable for fastening Simpson Strong-Tie stainless-steel products. Offering the same easy-driving, split-reducing installation of the standard SDS screw, these screws are made from Type 316 stainless steel. The stainless-steel SDS screws are appropriate for higher-exposure environments where maximum corrosion-resistance is required.

I’m buying more!
Size: Twin, Color: White
The quality of this product is amazing! It looks fantastic, super fluffy and comfortable, keeps accidents from getting onto mattress. It works so well! And is so worth the cost, I’m buying more for the rest of the beds in our house.

Fits great and very comfortable
Size: Queen, Color: White
I purchased because my cat is older and I need something waterproof. It fit my queen bed and my deeper mattress that usually needs extra deep mattresses. It looks nice and went on the bed easily. I have not had her test its waterproof feather yet. I am relieved I do not need to worry or put pee pads down for her. I reas some people find it hot and hear a squeaky sound. I have not experienced either. The padding is a nice addition. I was surprised by the soft padding feature as I was not looking for it. The price was great. I did not want to spend a lot of money for something that did not need forever given my cat is older with kidney problems now. I will not remove it even if it is not needed anymore because I like the cushion. I have purchased the Bedsure brand for other items and always been pleased with their price and quality. I recommend this product

Perfect to stop leaks or stains
Size: Twin, Color: White
This is a wonderful mattress protector that gets the job done. It absolutely prevents stains from leaking through to the mattress. The only thing I don’t like that could be improved is the size and lack of snug fit. It moves a lot but still does the job and is not too hot. It’s very soft and comfortable. Would be 5 star if it had a snug feature or bands to fit under the mattress. Worth it for the price and is long lasting.
