These custom binding posts were manufactured using 316 stainless steel material, with 3/8 coarse internal thread tapped as close to the head as possible and a T30 drive cold headed all the way through. The head diameter is 1.13" head height at .19" +/- .01". The shoulder outside diameter is set to .63" and measures .75" in length, with both dimensions also limited to a +/-.01" tolerance. 4340 alloy steel material was also considered as an alternative, offering greater strength when heat treated than the 316 stainless steel material version pictured here.
These custom low head slotted machine screws were manufactured domestically using 12L14 steel material and then run through a commercial black oxide process. Length under the head was set at .375" +/-.03", fully threaded with 8-32 thread pitch. The head height was set at .055", diameter at .265", slot width at .05", and slot depth at .042". Our internal part number for this item is MSF-0806-AF and while lead time varies quite a bit depending on production volume required, we typically budget 6-8 weeks from order confirmation.
These custom matched metallic silver painted machine screws are supplied to our long time customer in annual quantities of approx. 150,000 pieces using a revolving blanket purchase order. A standard off the shelf 18-8 stainless steel 10-24 X 1 machine screw is used, which is typically manufactured in Taiwan or mainland China, and the painting and sealing of the heads is done domestically in the USA to maintain the desired finish quality. Typical lead time for this type of painting work is 4-5 weeks from the placement of order.
We supply these custom aerospace compression springs to our aerospace components manufacturing customer. 17-7PH stainless steel material is used for the domestic production of these parts, per AMS 5673-F. Our production runs are typically in the smaller 500 piece quantity range for this specific spring, with lead time at 8-10 weeks. That lead time includes passivation per AMS QQ-P-35, and penetrant inspection per ASTM E 1417 Type I, Method A, Sensitivity L-3. Each one of those two processes typically takes about 1 week to complete.
We supplied our customer 10,000 pcs of these custom beryllium copper wave washers. They were manufactured domestically in the USA with a relatively long lead time of 14-16 weeks due to the material procurement timing involved. The ID measures .140 +/- .005" and the OD when flat measures .490 +/-.01". Thickness of the material is .020 +/-.0004" and the outside height post stamping is .080 +/- .080". Max load is 26.667 pounds and the max deflection is set at .015. Parts had to be vacuum aged for 2 hours at 600 degrees to complete the production process.
These custom precision flange bushings were produced domestically in the USA using 18-8 stainless steel material. The overall length measured .630" +/-.01" and the part incorporated both an external flange and an external flange per customer supplied drawings. The OD on the barrel portion is .5" and .585" at the external flange, both with the same +/-.01" tolerance. ID on the inside barrel portion is .45". These parts were used in an audio product manufacturing application by our customer.
