The main difference is lead
1605 usually means 16 mm diameter with 5 mm lead, while 1610 means 16 mm diameter with 10 mm lead. At the same motor speed, 1610 moves faster, while 1605 gives smaller travel per motor rotation and finer feed control.
When to choose 1605
Choose 1605 when thrust, low-speed smoothness, positioning resolution, or conservative load is more important. Small CNC machines, router Z axes, fixture adjustment, and general positioning often start with 1605.
When to choose 1610
Choose 1610 when higher linear speed, longer travel, or cycle time is more important. With higher speed, confirm motor torque, support method, critical speed, and end machining fit.
- Confirm whether the model is fixed as 1605 or 1610.
- Describe the axis: X, Y, Z, or adjustment axis.
- Provide travel, speed, load, and mounting method.
- Attach support model or end drawing if end machining is required.
Typical buyer situations
This topic usually appears in distributor stocking, repair replacement, machine retrofit, automation projects, and drawing-based purchasing. If a buyer sends only one model number, the supplier cannot judge the real use, packing risk, or whether machining upgrades are needed.
Details to confirm before quotation
To reduce repeated questions, the RFQ should cover product specification, use case, and delivery expectations together. The following points can be copied into the RFQ form or email.
- Purchase purpose: distributor stock, repair replacement, machine project, or sample testing.
- Specification: diameter, lead, overall length, thread length, nut type, and quantity.
- Machining: cut-to-length, end machining, and whether BK/BF, FK/FF, EK/EF, or other supports must be matched.
- Delivery: target quantity, expected lead time, packing, labels, shipping method, and whether shipment photos are required.
Common mistakes
A common mistake is asking only for unit price without application, quantity, or packing details. Another is sending photos without dimensions. This turns quotation into guesswork and can create errors in end machining, nut matching, or long-part shipping.
Next step
If the specification is clear, submit an RFQ directly. If the model or accuracy grade is still uncertain, describe the machine use and old part details so the supplier can recommend a standard part, bar stock, cut-to-length, or end machining route.
