Product and application brief
A pronged tee nut provides an internally threaded barrel with a flange and projecting prongs for a prepared host hole. It belongs to the nut family, with its host interface identified separately from the mating bolt thread.
Construction choices
| Choice or field | What to identify |
|---|---|
| Pronged drive-in form | The flange carries prongs while the barrel enters the prepared hole. Four-prong constructions are one catalogue form, not a universal requirement. |
| Catalogue identity | Bossard BN 225 identifies a drive-in tee nut for wood and plastics. A catalogue code is not a universal standard or proof of FastenerBridge supply. |
Host hole and seating side
Identify wood, board, composite or other proposed host material, thickness, hole preparation and edge distance in the assembly drawing. Include the flange seating side and bolt approach. Host suitability must be confirmed for the selected part and application.
Barrel, flange and prongs
Record barrel outside diameter and length, flange outline and thickness, and prong count, length and arrangement. Check protrusion and bolt clearance against the assembled stack rather than choosing by thread alone.
Not a machine-table T-slot nut
A machine-table or extrusion T-slot nut locates in a slot. A pronged tee nut locates in a prepared host hole. The similar name does not establish interchangeability. Nor is a pronged nut automatically a screw-in wood insert.
Thread and order definition
Specify thread system, diameter, pitch or TPI, hand and fit, plus the mating bolt reference. Material, finish and any required inspection evidence remain order-specific. No pull-out rating, tightening torque, installation force or compliance claim is supplied here.
Specification fields
| Choice or field | What to identify |
|---|---|
| Part identity | Exact catalogue reference or controlled drawing and revision; prong construction. |
| Thread | System, diameter, pitch/TPI, hand, fit and mating bolt. |
| Geometry | Barrel and flange dimensions, prong arrangement, units and drawing tolerances. |
| Host | Material, thickness, prepared hole, seating side, bolt access and clearance. |
| Order | Material/finish requirements, quantity, packing, destination and inspection documents. |
Common product questions
Is this the same as a T-slot nut?
No. A pronged tee nut uses a host-hole interface, whereas a T-slot nut locates in a slot.
Does every tee nut have four prongs?
No universal prong count is assumed. Identify the actual catalogue construction or drawing.
Does a matching thread prove suitability in a board?
No. Host material, hole preparation, geometry and assembly conditions require separate review.
