What it's used for
Decking subframe construction - hanging 47mm PAR joists from a bearer or ledger board
Floor joist trimming around openings such as stairwells and hearths
Underslung joist connections where a flush soffit is required
Light structural timber framing where a neat, load-bearing connection is needed without notching
Fitting and handling
Fix the hanger to the supporting timber first, ensuring it is plumb and square before inserting the joist. Use 30 x 3.75mm square twist nails through all pre-punched holes to achieve the rated load capacity - leaving holes unfilled will reduce performance. Store hangers in dry conditions prior to installation; although galvanised, prolonged exposure to standing water before fitting can accelerate surface oxidation on cut edges.
FAQ
What size timber does the 47mm mini joist hanger fit?
This hanger is sized for 47mm wide PAR timber, which is the finished planed width of standard construction timber. Always check your timber's actual finished dimension before ordering, as sawn sizes will be larger.
How many nails do I need per hanger?
You should fill every pre-punched hole using 30 x 3.75mm square twist nails. The rated load for the hanger is only achieved when all fixing holes are used. Using fewer nails will compromise the connection strength.
Can I use these mini joist hangers for outdoor decking in the UK?
Yes. The galvanised finish provides a reasonable level of corrosion resistance suitable for external decking subframes. For ground-contact or highly exposed conditions, check that your timber is also adequately treated to Use Class 3 or above.
