4-40 x 1 3/4 316 Stainless Steel Flat Head Socket Cap Screw supports flush-mounted construction in equipment that must be handled, wiped down, or positioned near moving components. The recessed head supports compact assemblies where a raised screw would interfere with nearby hardware. 316 stainless steel supports demanding service around salt spray, cleaning fluids, and many industrial washdown environments. The socket interface is practical for maintenance professionals working around equipment guards and enclosure hardware. It may be used on food and beverage machinery, inspection plates, and washdown-compatible equipment assemblies. Equipment builders can specify this listing when surface clearance and corrosion resistance are both design priorities. The defined size also supports consistent sourcing for production builds and field repairs. Call Cold Headers at 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote.
