Rail Bolt with nut
#3000-5 5" Rail Bolt. Great for rail terminations at wall where rosettes are used and you need the extra depth. 5" rail bolts are used to attach rails to walls when using rosettes, as they give more depth through the 3/4" rosette and 1/2" of drywall, for a secure fit. 5" rail bolts are also used in newel post anchoring (two per newel recommended).
5/16" x 5" Plain Steel Cone Point Rail Bolts.
