Specifications
The Torx mushroom barrel nut is the heavy architectural member of the family: a wide mushroom head with a six-lobe TX recess, sized M8 through M16. The collected tabulation shows heads of 30 mm (M8/M10) and 35 mm (M12–M16) over bodies of 14–20 mm, a constant 6 mm head-plus-collar height, and tabulated lengths of 15, 30, 40 and 50 mm with per-thread variants (M10 lists 10 mm and 25 mm, M12 lists 25 mm and 35 mm). A single TX50 tool fits every size in the series — one bit for the whole installation — and the six-lobe drive carries high torque without cam-out. A2 stainless steel is the collected standard material. The wide, smooth mushroom head is why this pattern is specified on playground equipment, street furniture and public installations: nothing protrudes to catch skin or clothing, and the head spans a compliant contact area on timber and soft-faced members.

Frequently asked questions
Why do playground and street-furniture specifications call for this barrel nut?
Two properties converge here. The wide mushroom head presents a smooth, low profile with no protruding edges to catch skin or clothing — a compliance concern in public equipment — and the six-lobe TX drive plus 30–35 mm head carries real torque into timber or soft-faced members without stripping or cam-out. One TX50 bit serves every size from M8 to M16, which matters on long installation runs.
What is the MOQ and lead time for this nut type?
The minimum order quantity is 10,000 pieces. Stock items ship in 3–7 days; non-stock items are confirmed at quotation. Common diameters in this nut type are widely stocked; confirm the exact schedule against quantity and size mix at quotation.
What should an RFQ for this nut type state?
State the designation (for example the barrel-nut SKU and head style), nominal thread size and pitch, overall barrel length or grip, material and finish (plain, zinc, or stainless where compatible), whether a through-hole or blind (closed) end barrel is required, the mating screw specification, required certificates, and quantity per size — plus destination country.
