SOCKET SCREWS
ISO 7380-2 Button Head Socket Screws with Collar
Collared button head screws provide a wider integral bearing face for panel and bracket assemblies.
Product Overview
The integral collar extends the bearing face around the button head and can help distribute contact on a flat panel or bracket. The rounded upper profile and internal hexagon drive suit assemblies where a conventional tall screw head would be intrusive. Check clearance for the collar and the permissible bearing pressure of the attached material before selecting the joint.
For an accurate quotation, specify the thread size, nominal length, material requirement and surface finish, together with the intended mating component. Dimensions, inspection requirements and the exact material and finish combination must be agreed before order confirmation.
