1 1/4″ SQUARE NUT, BOLT (1/2 of the casting sprue has the nut/bolt with a washer, 1/2 has no washer) NOTE: Measurements in inches are across the flat of the nut. These are cast as shown in this sample. Nuts/bolts are at the ends of the “teeth” of the comb. To apply to your project, we suggest drilling an appropriate hole to match the “stem” of the bolt, trimming it off of the comb, and finally pressing the stem into your hole. If cement is necessary, apply it from the inside. — Product No. 8 — Quantity:175 — Exterior Measurement: .026″ — Fits Within: NA — Additional Notes: Products may contain small parts and should be kept safely away from small children.
