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 Modified Button Socket Screws - 18-8 Stainless Steel Material

These custom modified button socket screws were made using standard off the shelf M3 X 0.5MM button socket cap screws.  The COTS version was modified to an overall length of 7.24MM, inclusive of the head height. The dog point prior to the radius start was set at a length of .015" and diameter of .090".  At the end of that dog point section the radius was machined at R 0.075.  Lead time for a similar modified part is typically 3-4 weeks from the attainment of the COTS version.

Custom Modified Socket Cap Screws - 2-56 X .745 With Machined Groove

In getting these custom modified socket cap screws made we started with standard off the shelf 2-56 X 3/4" socket cap screws in 18-8 stainless steel material - our customer required the length to be cut and chamfered down to .745" and a groove to be added 1/8" from the point.  The groove measured .052" to .054" in diameter and .061 to .071" in length.  Both modifications were relatively simple and we were able to get the parts ready within 2-3 weeks from purchase order placement.
