Fully threaded hex bolts to DIN 933 in A2 (304) and A4 (316) stainless steel - the most widely used bolt type in the Simfix range, covering M5 through M12 in 27 size combinations.
DIN 933 specifies full thread engagement from head to tip, which is the right choice when bolting into blind holes, thin material or any joint where you want thread contact along the full shank. Not to be confused with DIN 931 (partial thread), which handles shear load differently. In the trade these are also known as “hex set screws”, “set bolts” or “tap bolts” - all the same fastener.
A2 grade covers indoor, outdoor and general structural work. A4 (316) marine grade is correct for coastal, marine or permanently wet environments. DIY packs of 10 and Trade packs of 50 across all sizes. Free next-day UK delivery before 4PM.
