LOCKBOLT

A versatile fastening system that adds reliability and long service life to your product and equipment

Operating principle

LOCKBOLT

Vibration & shock can quickly impair the tightness of the joint & affect overall product performance.
By Fastening with Pl Lockbolts you are assured of a high vibration-resistant connection. The collar is swaged into the annular locking grooves of the lockbolt, forming a permanent Iock with uniform clamp, tensile and shear values.

Installation is simple, fast and virtually foolproof even with unskilled personnel.
Pl Lockbolts will pay off handsomely by lowering installation costs & improving product quality and reliability. Seeing is believing.Ask for a demonstration to fully appreciate this remarkable fastening system.

Pl Lockbolt pin is inserted in workpiece and collar is placed over pintail.

Nose assembly is placed over pintail.When the installation tool is activated, the nose assembly pulls on the pin & the swaging anvil forces the collar against the work-piece, drawing the worksheets tighter together.

As the pull on the pin increases, the swaging anvil moves over the collar,swaging the collar into the annular locking grooves.

Continued build-up of opposing forces by the installation tool causes the pin to break at the break-neck. The cycle of the installation tool is then reversed, causing the built-in release and ejector to push the tool off the installed fastener,A full swage is sufficient to ensure correct clamp-up.

The installed Pl Lockbolts, regardless of headstyle, provides a rugged, vibration-resistant fastener, with greater economy than is achieved with other methods.

Pl hi-strength LOCKBOLT pins

Steel - round, truss & countersunk head

Pl Lockbolt pins are ideal for use in mmmg, construction and rail road industries, as well as other heavy-duty applications where consistent, uniform clamp force is required. Totally resistant to vibration and stronger and more dependable than ordinary nuts and bolts or welded joints. Pl Lockbolts are available in diameters rangingfrom ½" to 1-3/8".

1. All dimensions are in millimeters (mm) unless otherwise noted.
2. To stay within the correct grip conditions, figures for "A" and "B" must be adhered to.
3. Figures in excess of "D" dimensions above typically indicates a worn - out swaging anvil and must be replaced immediately.
4. Swage depth lower than "C" above indicates either the swaging anvil is worn - out or lack of collar lubrication, or hardness problem with the lockbolt pin or the collar.
