ANSI/ASME B18.6.1 Wood Screws (Inch Series)

Documents

Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.

Quotation

• The fastener family (ANSI/ASME B18.6.1 Wood Screws (Inch Series)) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
• Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
• Quantity per size and your target delivery date.
• Destination country, and any required documents (for example a mill test certificate) so the quote includes them.

Sample & supply

Minimum order quantity is 10,000 pieces. Stock items run 3–7 days. Quantities or variants outside the standard range are confirmed at quotation.

Storage & shipping

Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.

How do I choose between flat, round and oval head patterns, and which driver does each size take?

Choose by seating geometry, not preference. The flat head (countersunk) sits flush or below the wood surface — the collected table gives head diameter A (.225/.195 at #4 up to .544/.485 at #16) so the mating countersink or the screw's own cone can be sized; use it where a protruding head would foul sliding parts or finish surfaces. The round head sits proud on the surface and carries the largest bearing diameter for its size at the shallowest height — the choice for thin material where countersinking would weaken the joint, and for applications where the head is deliberately visible. The oval head blends both: countersunk like a flat head but with a rounded top that leaves no sharp edge — the collected table carries its side height and total height separately for exactly that trim reason. Driver size is tabulated per size rather than estimated: #2–#4 take a #1 Phillips bit, #5–#9 take #2, #10 and up take #3 in the flat and oval tables (the round-head table shifts #10 to #2 — read the table for the specific pattern you order, and note the #12/#14 flat-head rows share identical recess dimensions in the source). One gap to quote honestly: the round-head ladder in the collected data ends at "14n" and skips #3 — quote those sizes at RFQ rather than reading them off the table.

Cut thread or rolled thread — does the difference matter for my joint?

Yes, in two measurable ways the tables capture. Body diameter: the cut-thread table column and rolled-thread column differ at every size — rolled-thread body diameter is consistently smaller (for example .075/.064 at #2 against .090/.079 cut, .214/.203 at #16 against .272/.261). The cut-thread shank tapers toward the point while the rolled shank is constant-diameter, which is why the rolled body sits inside the thread envelope. Thread length: cut thread runs about two-thirds of the screw length; rolled thread must reach at least four times the basic screw diameter or two-thirds of length, whichever is greater — so at short lengths a rolled screw carries proportionally more thread, and screws too short for that minimum are threaded nearly to the head. Practically: a rolled-thread screw gives a stronger shank (thread rolling work-hardens the surface) and more consistent driving; a cut-thread screw's tapered shank seats well in hardwoods and matches legacy holes. Specify the variant on the order — the body-diameter difference is large enough that an interchange without checking the table can change the fit in an existing hole.

What is the MOQ and lead time for these screws?

The minimum order quantity is 10,000 pieces. Stock items ship in 3–7 days; non-stock items are confirmed at quotation. Common sizes in these designations are widely stocked; confirm the exact schedule against quantity and size mix at quotation.
