Custom Low Head Metric Screws – M3 X 0.5MM X 3.25MM
Custom low head metric screws manufactured domestically using 303 stainless steel material. The 1/16 hex drive was broached with a 1.5MM drive depth. Heavy torque blue thread locking patch was applied to conform to a .60 to .33 Nm minimum torque testing. Head height measured 1.75MM and the width at 9.65MM. The rounding around the edges of the head was set to R 0.020. Production samples were provided for customer testing and approval prior to commitment to a full production run. Lead time for production is 8-10 weeks from confirmed order. Certificate of conformance, First Article Inspection Report, material cert, and passivation cert were required with the parts per our customer’s request.
Large quantities of these custom metric hex socket screws would be best supplied on a 12 month blanket purchase order basis. The Blanket Order concept allows the customer to access the large quantity cost savings without paying upfront for the entire large quantity order. Instead we take on the burden of carrying the bulk inventory and only release the parts as needed, or often on a pre-scheduled basis provided by the customer.
