In plain language, it is how OEMs make special screws, bolts, studs, and related parts from a print when catalog geometry will not fit the assembly.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Made-to-print fasteners and other non-standard fasteners share that same idea: the controlled drawing owns the geometry. A sample may help reverse-engineer unknowns, but production still needs controlled dimensions and a revision owner.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">This article covers catalog-versus-custom decisions, cold heading, precision machining, thread rolling, finishing, and cross-family RFQ packaging.

In plain terms, the blank is formed in dies instead of being carved from bar. After heading, external threads are commonly formed by thread rolling, a cold-forming process that differs from cut threads that sever grain structure.<\/p>\n<figure style=\"margin:26px 0;text-align:center\"><img decoding=\"async\" style=\"max-width:640px;width:100%;height:auto;display:block;margin:0 auto;border-radius:8px\" alt=\"Square-head step shoulder screw showing non-catalog shoulder geometry\" src=\"https:\/\/thfasteners.com\/wp-content\/uploads\/2026\/08\/cfm-uniq-body-process-square175.webp\" \/><\/figure>\n<blockquote>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Tip:<\/strong> Practitioner discussions prefer roll-formed threads over lathe-cut threads for large-scale manufacturing because forming is faster and roll-formed threads are stronger.

It is not DIY lengthening of a catalog screw.<\/p>\n<h3 style=\"margin:28px 0 12px\">When should I leave catalog parts for custom manufacturing?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Leave catalog parts when geometry, thread layout, material, finish, or assembly function forces compromises standard hardware cannot fix. If a catalog match already covers length, drive, and head, stay on the catalog path first.<\/p>\n<h3 style=\"margin:28px 0 12px\">Cold heading vs machining\u2014how do I choose?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Choose cold heading when the blank is formable and volume can support die economics. Choose machining when geometry is complex, undercut, or still in prototype volumes where die commitment is the wrong cost. Hybrid routes are normal; state quantity and critical features so suppliers can propose the mix.<\/p>\n<h3 style=\"margin:28px 0 12px\">Why does thread rolling matter on the RFQ?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Thread rolling forms external threads by cold forming after heading, while cut threads remove material and sever grain. Putting rolled versus cut on the print prevents suppliers from quoting different process assumptions under the same part number.<\/p>\n<h3 style=\"margin:28px 0 12px\">What belongs in an OEM RFQ package?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Include family\/geometry, drawing revision, thread designation with tolerance class when fit matters, material, finish, quantity\/EAU, inspection expectations, and clear headed\/machined and rolled\/cut notes.
