10-32 x 2 1/4 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert should be ordered by total screw length because the head is part of the measurement. Overall-length measurement matters on countersunk joints because the head occupies part of the thickness stack. A countersunk head bears on the cone rather than a broad underside, so clamp load should not be treated like a full socket head cap screw.
This size is often reviewed for washdown covers, processing guards, and inspection doors when stainless material, a flush head, and locking friction are all specified. Plain 18-8 Stainless Flat Head Socket Cap Screws may fit torque-once joints where a nylon insert is not required.
Slight magnetism from cold working can be normal for 18-8 stainless, so final material selection should reflect the assembly conditions. Cold Headers can handle supported non-catalog pellet-size requests through in-house pelletizing.
