Mix and Match Mercury Glass Sphere 1 in. Curtain Rod Finial in Matte Black (2-Pack)

A:  Hi whitequeen, Yes, the standard screw specification size we use is as follows: 1/4” thread and 28mm length.

A:  Hi Thread: thanks for the question as many are often confused about all these measurements. To keep things simple, especially for the Americas, we prefer to refer to our finial end screw or bolt size as 1/4“ (inch). (m5 and m6 refer to metric thread sizes while the UK Imperial measurements refer to it as TPI – “threads per inch”) But it seems to work best for us just to say our finial end screw is a standard 1/4“ (inch) diameter screw or bolt. Hope that works for you.

A:  Hi Mariame, Yes, if you look at the product page one of the product photos show the two finials clearly with the ¾” standard screws attached on the ends.

A:  Hi Sandy, the attachment screw on the bottom of the finial is the standard screw size of 1/4 “ (in.) Most rods use this standard size screw so it can be used with various rod diameter s if the receiving screw end of the rod is the same 1/4 “ (in.).
