"wasn't sure these be man enough but used them to fix a roof support to an external wall, for a small lean to. They worked perfectly, just be sure to drill the right size hole though...too big and they don't work! Cheap and perfect for the job"
"Great all round product for whatever you are fixing to solid surfaces. You can be assured it's well fixed not going to fall off. Being a plumber I fix a lot of heavy ceramic's to wall's so I need to know it isn't going to move and this guarantee's it."
"THESE THRU BOLTS ARE EXCELLENT VALUE FOR MONEY AND EASY TO USE , EVEN THE LESS EXPERIENCED DIY ENTHUSIAST WOULD HAVE NO BOTHER USING THIS PRODUCT. WE HAVE USED THEM SEVERAL TIMES AND HAVE HAD NO BOTHER WITH THE INSTALLATION AND QUALITY OF THEM."
