Specifications
The two-hole pig nose nut is the plain spanner-drive member of the security family: a rounded nut whose flat face carries just two round holes, engaged only by a matching two-hole driver — an ordinary spanner, socket or pliers has nothing to grip. The collected tabulation runs M5 to M10, with head diameters stepping from 12 mm to 22 mm, nut heights from 4.2 mm to 8.0 mm, and the hole pair growing from 2.0 mm diameter with a 2.3 mm minimum depth at M5 to 3.5 mm diameter and 3.8 mm depth at M10. A1 stainless steel is the standard material, with steel available to order. The fixing is reusable — install and remove it as often as the driver allows — which suits panels and enclosures that need legitimate servicing. Two honest cautions come with the drive: the two-hole pattern is more prone to cam-out than pin-hex or Kinmar-style drives, and the drivers themselves can bend or break after prolonged use, so the source advises keeping a spare tool. Security fencing, cladding panels, plant enclosures and public furniture are the typical ground.

Frequently asked questions
When is a two-hole pig nose nut the right security choice?
When the joint must be reopenable but not by casual hands. The two-hole face gives a standard spanner nothing to turn, yet the dedicated driver reopens the joint for servicing — so it fits access panels, cladding and enclosures with legitimate maintenance schedules. If the joint must never reopen, a permanent pattern like a shear nut is the better pick; if drivers will see heavy daily use, consider a more cam-out-resistant drive such as pin-hex.
Why keep a spare driver for this nut?
The collected page is explicit that two-hole drivers are prone to bending or breaking after prolonged use, and recommends purchasing a back-up. Losing the driver does not lock the joint permanently — two-hole drivers are a known tool category — but it does stall maintenance, so a spare in the tooling drawer is cheap insurance for any installation beyond a handful of 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.
