• ③ Lead (mm): 01 = standard ball lead 1 mm (01K = non-standard 1 mm)
• ④ Ball Return Type: D = Deflector; S = End deflector; T = Return tube; C = End-cap
• ⑤ Custom Option (non-standard)
• ⑥ Threaded Section Length (mm): decimal point indicated by "_" in part number
• ⑦ Thread Direction: R = Right-hand; L = Left-hand; LR = Right- & Left-hand
• ⑧ Total Screw Length (mm): decimal point indicated by "_"
• ⑨ Accuracy Grade: C3 = JIS C3; C5 = JIS C5; C7 = JIS C7; C10 = JIS C10
