Custom Large Anchor Bolts - F1554 Grade 36 Material, Galvanized

These custom large anchor bolts were manufactured domestically using F1554 grade 36 material for the threaded anchors, F436 material for the washers, and A563 material for the nuts.  All parts were 2" in diameter with coarse thread, with galvanized finish.  The large anchor bolts measured 6 feet in overal length and each was provided with 5 heavy hex nuts and 3 washers.  Production was done with an expedited rush option to be completed within 7 business days.  Material certs were provided with the parts.

Custom Modified Grade 8 Machine Screws - Special Head Shape

These custom modified grade 8 machine screws were made using 5/16-18 X 1-1/4 Grade 8 hex head cap screws in grade 8 steel material with zinc/clear finish.  The head of each COTS part was machined to the shape seen here, with the head height at .190" +/-.005" and head diameter at .485" +/-.005".  Single flat .42" section was incorporated at one section per our customer's provided sample piece.  Total of 300 pieces were modified on this specific production run and the lead time was approximately 2 weeks from the order receipt.

Custom Double End Shoulder Studs - A193 B7 Material

These custom double end shoulder studs were manufactured domestically using B7 material with plain finish.  1" coarse thread was incorporated on one side at a length of 1-1/4".  1-5/8" of 3/4" coarse thread was cut on the other side of the stud, with the shoulder machined to a diameter of .75" +/- .01".  Overall length of the double ended stud is 4" +/-.01" and in plain finish this part can be produced relatively quick with a lead time of 2-4 weeks depending on the production volume required.  Material certs were provided with the parts per customer's requirements.

Custom Low Profile Socket Head Screws - 302 Stainless Steel With 6 Lobe Drive

These custom low profile socket head screws with a  6-lobe (torx) drive were manufactured domestically using 302 stainless steel material with a commercial passivated plain finish.  5,000 pieces of two sizes were produced: M10 - 1.5M X 65MM with a T-45 drive size and M8 - 1.25M X 65MM with a T-30 drive size.  26-30MM of thread was incorporated on the larger version and 22-25MM on the smaller diameter part.  The low profile & 6-lobe drive combination is relatively tricky, especially for these larger diameters as additional controls in tooling are required to avoid flowering on the outside profile of the head.

Custom Galvanized Anchor Bolts - A36 Steel, Galvanized

These custom galvanized anchor bolts were manufactured domestically with a rush timeline using A36 steel material with a galvanized finish.  7 inches of 1"-8 coarse thread was incorporate on the long leg, with cut thread as opposed to a rolled alternative.  Overall length was set at 17" and the length of the short leg on the outside is 3".  Two galvanized nuts and washers were supplied per anchor bolt.

Custom Low Profile Torx Machine Screws - 18-8 Stainless Steel

These custom low profile torx machine screws were manufactured domestically using 18-8 stainless steel material, at production volume of approximately 5,500 pieces.  T10 size 6 lobe drive was incorporated and the head diameter at .262" +/-.01" and head height at .263" +/-.01.  6-32 thread was selected for the .185" of thread, followed by a lead point measuring .090" +.000/-.002 in diameter and .050" +.020/-.000 in length.  Parts were passivated per MIL QQ-P-35 Type II to complete the production process.

Large Custom Round Spacers In Stainless Steel Material

These large custom round spacers were manufactured domestically using 18-8 stainless steel material with plain finish - no passivation was required either for these specific parts.  The outside diameter was set at 1-1/2" +/- .01" and the inside diameter at 1/2" +/- .01".  Overall length measured 2" with the same tolerance as the other dimensions.  Slight chamfer was added on both sides to smooth out the sharp edges.  

Custom Long Compression Springs In 17-7PH Material - 30.331 Overall Length

The production of these custom long compression springs in 17-7PH material was run at a relatively small batch of only 25 pieces.  17-7PH material was used per AMS 5678 and all production work was done domestically with all secondary processes done with NADCAP certified facilities.  A first article inspection report (FAIR) was provided as well with the parts together with all other certs.  .060 +/-.0015" diameter wire was used to make this part and the ID/OD was set to .78"/.90".  Parts were passivated per AMS 2700, method 1, type 2 or 8 with full certs to complete the production process spanning approximately 7-8 weeks from start.

Custom Precision Steel Pins - 1018 CRS Material

These custom precision steel pins were manufactured domestically for our customer involved in water treatment product manufacturing.  1018 CRS material was used with plain finish.  The drive-less head measures .060" in height and .290" for the diameter, +/-.005".  The shoulder portion was the most critical with a diameter of .195" +/- .001" and a slight 45 deg by .02" chamfer.  Overall length of the shoulder shaft was set to .460".  Production is typically done at 5,000 pieces at a time.

Custom Internally & Externally Threaded Studs - Medium Carbon Steel Material

Production of these custom internally and externally threaded studs was run at approximately 10,000 pieces, in medium carbon grade 5 equivalent steel material.  The specific hardness requirement was set to 25-35 HRC.  The custom threaded studs had an overall length of .75" +/.02" with a 45-50 degree tapered point on one side.  Slotted drives were incorporated at both sides for optimal flexibility in our customer's application.  1/2-13 thread was rolled on the outside and 1/4-20 thread tapped all the way through.
