Workshop Warehouse Setscrews H/T Grade 8.8 M12 X 25 (HSS56)

Description

Genuine Workshop Warehouse · Part no. HSS56

These Workshop Warehouse HSS56 setscrews are M12 x 25, grade 8.8 to DIN 933, in zinc plated steel with a hex head. A short M12 like this is for heavy plates and mounting feet bolted straight into a deep tapped hole or a thick captive nut; the pack weighs 1.75 kg.

Good to know

• Is a 25mm M12 long enough? Only where the part you are clamping is thin: after the plate and washer, at least 12mm of thread should be engaged in steel, more in aluminium.
• How do I check it is M12? Measure across the thread, which reads close to 12mm, and compare the pitch with the old screw before you buy a full pack.
• What spanner will it need? Check the head across the flats before starting, as head sizes vary between standards; a six-point socket grips a tight screw better than a twelve-point one.

Which one?

For longer M12, Workshop Warehouse HSS74 is 75mm and Pearl PHS336B is 50mm in a box of 50; or see Connect Hi-Tensile Set Screw – M12 x 60.0mm – Pack of 50 (31319).
