About Capabilities HORST Cycling Careers Contact/RFQ Shop Thread Rolling and Grinding Services What is Thread Rolling? Roll Threading Capabilities and Approvals Thread types: 60º thread form/machine screw type threads, Safety Critical Threads Forms: UNR, UNF, UNC, UNJ, UNJF, UNJC (classes 1A, 2A, 3A, 5A) Metric forms: ISO and DIN (classes 6g and 4g6g) Sizes: .078 inch (2mm) to 2.500 inch (63mm) Material Hardness: Up to Rc45 depending on material type and size Approvals include: AS Specifications (e.g. AS7460, AS7466), Pratt & Whitney Aircraft, GE Aviation, Collins Aerospace, Kaman Aerospace, Bell, SpaceX Thread Inspection We maintain a large inventory of English standard and metric thread gages. Typical industry specifications include AS8879, MIL-S-7742, Handbook H28, and ANSI specifications. Thread Laboratory & Testing Our in-house laboratory performs metallographic examinations of rolled threads to aerospace, military, and customer specifications. We test for external and internal defects. Centerless and Cylindrical Grinding The highest quality threads are produced from the highest quality blanks. Most customers supply their machined components at a specified oversized diameter. Then we develop the correct size and grind the finished diameter as part of our preparation process. We also offer centerless and cylindrical grinding services for non-threaded components. Knurling Thread rolling equipment is well suited for producing high quality knurls (straight, diagonal, and diamond). Knurls are essential characteristics for tooling and components in a variety of industries, but especially important for surgical and other medical tooling and devices. Rolled knurls are superior in finish, form, and dimensional consistency to knurls formed by cutting or bump rolling on lathes and screw machines. Let us help you with your knurling requirements. Roll Knurling Knurl Types: Circular and Diametral Pitch, Straight, Diagonal, Diamond Circular Pitches/TPI (teeth per inch): 12, 16, 20, 25, 30, 35, 40, 50, 80, special Diametral Pitches (DP): 64, 96, 128, 160, special Sizes: .040 inch (1mm) to 1.500 inch (38mm) Material Hardness: Up to Rc42 depending on material type and size See our Thread Rolling, Roll Knurling, & Grinding Services Line Card for a more technical summary of our capabilities.
