Specifications

The scroll security barrel nut pairs the wave-profile spanner drive with the barrel-nut (sex bolt) body: a female, internally threaded sleeve whose flange carries the scroll pattern, so the mating screw is hidden inside the joint while the head still refuses every standard tool. The collected tabulation mirrors the scroll nut tables — M2 to M48 metric (head heights 3.2–14.2 mm, head diameters 7.9–38.0 mm) and No. 2 to 7/8" imperial — with the same dash-celled gaps. The material spread is wider than the standard scroll nut: A1 and A4 stainless, mild and high-tensile steel, case-hardened steel and plastic. Two practical differences from the catalogued scroll nut matter at ordering time: this barrel-nut line is made to order only — the source states there is no stock chart, though some sizes may be held — and the drive tool is restricted, distributed only to registered purchasers of the fixings. Panels and assemblies that must present a tool-proof face yet come apart for the rightful owner are its ground.

Frequently asked questions

How does a scroll barrel nut differ from a standard barrel nut?

The drive, not the body. Both are female internally threaded sleeves that pair with a matching screw to clamp panels from inside, but the standard barrel nut turns with a hex key or spanner, while this one presents a waved scroll face that only a restricted tool engages — and which the source distributes only to registered purchasers. You keep the sex bolt's hidden-thread, clean-face joint and add the tamper-resistance of the scroll drive.

What should I plan for when ordering this line?

Lead time, because the collected page states the barrel-nut line is made to order with no stock chart (some sizes may be held — confirmed at enquiry). State the thread, grip length, material — including the case-hardened option where attack resistance matters — and whether the mating male screws are needed with matched head dimensions. The restricted drive tool is supplied through the same registered channel as the fixings.

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 spanner-drive SKU and head style), nominal thread size and pitch, material and finish, whether the matching drive tool or bit is needed, the mating screw or stud specification, required certificates, and quantity per size — plus destination country.
