DIYUK M8 x 30mm Black Oxide Hex Socket Countersunk Bolts, DIN 7991 Grade 10.9 Carbon Steel, Allen Key Flat Head Screws, Pack of 10

Flush-fit, snag-free finish: the 90 degree countersunk head seats flush with, or just below, the surface rather than standing proud. Manufactured to DIN 7991 from carbon steel in property class 10.9, with a black oxide finish. Allen key drive: the fully recessed hex socket lets you tighten straight down the centre of the bolt, even in tight or hard-to-reach fixing points. Ten sizes from M4 x 8mm to M8 x 35mm, fully threaded, in packs of 2, 10, 50 or 100; head and hex key sizes listed for every size. Fixings for flat-pack furniture and cabinetry, 3D printer and machine frames, electronics enclosures and general workshop and DIY jobs.
