"As a retired engineer, I have used steel studding all my working life for making up experimental equipment, clamping on machine tools etc. A few lengths of studding held in stock. plus the assocated nuts and washers (also available from Screwfix) provide an easy solution to clamping problems, instead of using a long bolt. Lets face it, you will never find a bolt, 1000 mm long.
The Screwfix product is fantastic, very economic and extremely versatile."
