Custom Stainless Steel Double End Studs - 1/4-20 & 10-32 Thread in 304 Stainless Steel
We provided our customer a small batch of these custom stainless steel double end studs at just over 100 pieces.  They wanted to replicate existing parts but did not have any drawings or prints.  We used a sample piece provided to replicate all dimensions to a +/-.01" tolerance.  1/4-20 thread is incorporated on the larger diameter side and 10-32 on the other, with approximately half the thread turned down into a dog point.

Custom Geomet Coated Washers - M5 Flat Washer With Geomet 500 Finish

Custom Geomet Coated Washers - M5 Flat Washer With Geomet 500 Finish
These custom Geomet coated washers are produced and finished domestically using 3 runs of Geomet 500 coating.  The washer itself is made using HV-140 steel material and is dimensionally almost identical to a standard DIN125A flat washer, with the thinner height being its only variation.  The ID is 5.3-5.48MM, the OD is 9.64-10MM, and the thickness is 0.8-.85MM.  A large variety of different Geomet coatings are available, not to mention the Xylan, Magni, and other trademarked finish processes at your disposal.  Lead time to get the plain flat washers produced is typically 8-12 weeks, and another 3-4 weeks for the Geomet 500 coating process.

Custom 32tpi Socket Head Cap Screws - 4140 Material With 37-44 Hardness And 1/4-32 Thread Pitch

Custom 32tpi Socket Head Cap Screws - 4140 Material With 37-44 Hardness And 1/4-32 Thread Pitch
These are custom 32tpi socket head cap screws we supplied to our automotive prototyping customer.  4140 plain alloy material was used to produce a small batch of just 25 pieces domestically in the USA.  The 1/4-32 thread pitch was really the only tricky part requiring a custom production run.  Speed was absolutely critical to our customer and we were able to get the parts made and shipped within 2 weeks from order confirmation.

Custom 316 Stainless Tapered Head Screws - 10-13 X 1.75" Thread Forming Screws With Gimlet Point & Custom Rounded Tapered Hex Head

Custom 316 Stainless Tapered Head Screws - 10-13 X 1.75" Thread Forming Screws With Gimlet Point & Custom Rounded Tapered Hex Head
These custom 316 stainless tapered head screws turned out to be a very tricky part - while the 10-13 thread and gimlet point were easy to incorporate, the custom head was a tough problem to solve.  A 10 degree taper was required on the hex flats and the corners rounded.  A rounded profile on a vertical cross-section of the head was also required to allow the screw to rotate while still maintaining hex head engagement.  It took three rounds of tooling to finally get the head shape just right and fit the application requirements our customer desired.  Domestic production of this part was set at 50,000 pcs with a lead time of 8-12 weeks.

Custom Small Diameter U-Bolts - 4-40 X .75" Fully Threaded Round U-Bolts In Low Carbon Steel Material


Custom Small Diameter U-Bolts - 4-40 X .75" Fully Threaded Round U-Bolts In Low Carbon Steel Material

These custom small diameter u-bolts are the more unusual u bolts we have supplied over the years - the one and only time we had to get fully threaded u-bolts manufactured.  Typically only a partial length of each leg is threaded, whether cut threads or rolled, but in this case our customer specifically requested a fully threaded version.  2,000 pieces were run through a domestic production process with a lead time of 5-6 weeks.  4-40 thread was incorporated with the inside width at .57 inches and inside length at .75 inches.

Custom 4140 Flat Socket Head Screws - Custom 1/4-28 X .595" Flat Socket Screws For Aerospace Applications

Custom 4140 Flat Socket Head Screws - Custom 1/4-28 X .595" Flat Socket Screws For Aerospace Applications
These custom 4140 flat socket head cap screws were produced domestically for our aerospace customer using AISI 4140 alloy steel material per AMS 6349.  Heat treat to 160-180 ksi per AMS 2759 was performed to finalize the production process.  Magnetic particle inspection per ASTM 1444 (Type I, Meth A, Sens Lev 3) was performed after the machining process was completed.  Lead time for this part varies significantly based on how busy the manufacturing and testing facilities are at the time of start.
