The Alcone Engineering Inc. HBS makes use of a Socket Head Cap Screw, SHCS instead of a hex head bolt. The SHCS provides improved access to the bolt head for installation. The head of the SHCS is as small in outside diameter as the reduced head bolts provided by header manufacturers. Further the SHCS allows the use of a "ball-driver" wrench which can engage the SHCS at a significant angle (28 deg.) relative to its centerline. The ball-driver is itself smaller in diameter than the head of the SHCS, further easing access. A picture of the three components of the system is shown below. The Alcone Engineering Inc. Header Bolt System solves the three major problems associated with exhaust header installations:

Problem : Access to bolt heads is restricted

Solution : SHCS allows use of ball driver to facilitate access to header bolt.

Problem : Bolts loosen over time

Solution : Cross-drilled head for safety wire or hitch pin

Problem : Header flanges distort

Solution : Heavy washer, specially shaped to clear primary tube, reinforces header flange, easy access to header bolt heads ensures that bolts are actually installed and torqued to proper levels.

NOTE: That all the pieces are large and easy to handle no small circlips or cotter pins to drop under the vehicle. Patent pending.
