Specifications
TX32 is the gentlest of the grub points and the deepest-reaching: a flat, square-ended tip that distributes its compressive holding force evenly instead of digging in, which is what you want against soft materials, ground flats and any surface where a cup point’s bite would be damage. The collected page names exactly those uses, and adds the drive argument it shares with the whole pin-TX line — no cam-out at maximum torque, medium security from the centre pin, installed and removed only with the matched insert bit. The tabulated range is the broadest in this batch: M1.6 through M24, with socket depth and socket width figures starting at M3 (the M1.6–M2.5 columns carry dashes, so no tool claims are made for them), and a metric availability matrix marked available from 2 mm to 190 mm — M10 alone running the full 190 mm, with M12/M16 covering to 120 mm and the M24 column stopping at 100 mm. The imperial table (No.2-56 through 3/8-16, 1/8″–2″) is tabulated but its cell markers are an icon the page’s legend does not define, so imperial availability stays at quotation. Supply is stated in steel, A2 and A4 stainless steel as standard.

Ordering & documentation
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 (TX32 6-Lobe Pin TX Security Grub Screw — Flat Point) 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.
Frequently asked questions
Flat point versus cup point — what actually changes at the tip?
How the holding force lands. The flat point presses a full flat circle against the surface, so nothing digs in — right for a hardened and ground shaft, a soft plastic boss, or a part that gets adjusted repeatedly, because there is no crescent-shaped bite to wear into a lip. Cup point (TX28) deliberately digs a shallow ring for maximum rotation resistance on surfaces that can take the mark. If your set screw sits against a machined flat, flat point is the pairing the geometry assumes; if it must never slip on a rougher surface, cup wins.
How far does the range actually go?
Farther than most buyers will ever need: the metric matrix marks available from 2 mm to 190 mm of length, with M10 the deepest at 190 mm and M24 marked to 100 mm. Thread sizes M1.6 through M24 are tabulated, though the three smallest sizes carry no socket depth or tool figures on the source table — those are quotation lines for dimensions as well as availability. Imperial sizes are tabulated to 2″ but their markers are not defined by the collected legend, so treat imperial as confirm-at-quotation.
What should an RFQ for TX32 state?
State the designation (TX32 6-lobe pin TX flat point grub screw), thread size and length, material (steel, A2 or A4 stainless as standard), the mating surface (flat against ground flats, soft material call it out), quantity per size, and required TX-series bits. If you need imperial sizes, ask for stock confirmation per pair — the source tabulates them without a legend-defined availability marker.
