FAQ
Full thread or partial thread?
DIN 933 hex cap screws are threaded to the head. DIN 931 screws have a plain shank under the head. We stock DIN 933 full thread; DIN 931 partial thread is available, please contact us.
What is A2 stainless steel?
A2 is the metric (ISO 3506) name for 304 type stainless steel, the same family as 18-8. It resists rust outdoors, in wet areas and in washdown use. A4 is the 316 type, for salt water and chemicals.
How do I stop stainless threads from galling?
Stainless threads can seize (gall) when tightened fast or dry. Use an anti-seize compound, tighten at a slower speed, and do not over tighten.
Are metric and inch fasteners interchangeable?
No. Close sizes such as M6 and 1/4" or M10 and 3/8" have different diameters and thread pitches, and they will cross thread. Use metric nuts and washers with metric bolts and screws.
