S-5 M8-1.25x40mm Flanged Bolt

The S-5! M8-1.25×40mm Flanged Bolt is an extended-length fastening solution from S-5! designed to be used with clamping systems, utility rails, and brackets when standard bolt lengths are not sufficient. Threaded with an M8 bolt at 1.25 mm pitch, 40 mm in length, and featuring a flanged head (≈13 mm hex socket size), this bolt ensures secure attachment while distributing load via its integral flange. It’s compatible with regular and mini S-5! clamps, GripperFix Utility hardware, and any app where extra thread length is required. Sold individually or by the box (200 pieces per box).

Q: What difference does the 40 mm length make vs shorter bolts?
A: It provides additional thread penetration for thicker assemblies or when stacking hardware, avoiding bottoming out or insufficient thread engagement.

Q: What thread pitch and diameter is this bolt?
A: M8 diameter with 1.25 mm thread pitch (metric fine thread).

Q: Is the bolt’s head flanged, and what purpose does that serve?
A: Yes. The integral flange under the head acts like a washer, spreading load and preventing localized compression or damage.

Q: How many bolts come in a full box?
A: A full box has 200 pieces.
