Custom Long Machine Screws - 302 Stainless Steel

 Almost 20,000 pieces of these custom long machine screws were manufactured for our injection molding customer, made using 302 stainless steel material with plain finish.  4/40 thread was incorporated with 1" of usable thread minimum on each screw.  Overall length was set to 4.625"-4.725" and the head was a standard philips pan head for a #4 machine screw.  Concentricity was the more difficult aspect of these parts, with the combination of length and #4 diameter making it almost impossible to keep the parts straight after packaging.  

Custom Cone Point Screws - 8-32 Slotted Machine Screw In 18-8 Stainless Steel

These custom cone point screws were manufactured using 304 stainless steel material with plain finish.  8-32 fine thread was incorporated with the overall length of the threaded portion and the cone point set at .2925"-.3125".  The head diameter was .306"-.322" and slot depth at .045"-.058".  Head height was set at .085"-.096".  Production was completed at just over 13,000 pieces within 8 weeks from order.

Custom Low Head Metric Screws - M3 X 0.5MM X 3.25MM With Thread Locking Patch in 303 Stainless Steel Material

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.

Custom 6-Lobe Socket Head Cap Screws - 6-32 X 1-1/4 In 18-8 Stainless Steel Material

Custom 6-lobe socket head cap screws manufactured domestically in 18-8 stainless steel material at approximately 8,000 pcs.  Our customer wanted us to provide these custom screws in black oxide finish after running them through ASTM A967 passivation.  Partial unthreaded shoulder was incorporated and the thread was rolled instead of the cut alternative.  Lead time for similar projects is currently running at 8-12 weeks from order confirmation.

Custom Deep Recess Phillips Drive Screws - #8 X 2" Phillips Pan Type A Sheet Metal Screws

At first glance these custom deep recess phillips drive screws seem like ordinary sheet metal screws.  For the most part that is true - the Type A thread and head dimensions are essentially per IFI specs without any modifications.  A closer look however will reveal a significantly deeper recess in the phillips drive.  Standard #8 phillips drive for a pan head reaches a depth of .108" while this custom part has a recess depth of .120" to .122" - a significant difference when it comes to improved engagement and faster/easier use on the production floor.  This improvement in speed and engagement was the main driver behind our customer's request for this modified sheet metal screw, particularly important when some of the depth is used for paint when the screw heads are painted a variety of different colors.

Custom Unique Thread Pitch Screws - 3/8-20 X 1-1/4 Socket Head Cap Screws in 18-8 Stainless Steel Material

These custom unique thread pitch screws were one of the stranger projects that we came across - it was the first time in over 20 years that someone requested a 3/8-20 thread pitch.  We had the custom screws manufactured domestically at just 40 pieces using 18-8 stainless steel material.  The lead time was at approximately 3 weeks from order confirmation.

Custom Stainless Steel Socket Cap Screws In 303 Stainless Steel - 8-32 X 4-1/2"

These are custom stainless steel socket cap screws made domestically using 303 stainless steel at just 102 pieces.  We supply this part to our long time aerospace customer approximately once a year with full paperwork.  It measures 8-32 X 4-1/2 and had a relatively short lead time of 1 week for production.  Our internal part number is SC-008068-I.

Custom Machined Flat Head Screws In 303 Stainless Steel

These are custom machined flat head screws made domestically in the USA using 303 stainless steel material.  The unique application required the custom screw to have a stop shoulder machined and a 30 degree angle under the head.  10-24 thread was used for the threaded area and the head diameter was maintained at .312" +/-.005.  We supplied just 10 pieces of these custom machined screws for prototype purposes before our customer commits to a larger quantity.
