 BALL LOCK PINS

FEATURES: Precision alignment pin with a ground shank. This popular single-acting type is positive locking until released by pushing the button, which moves the center spindle forward to allow the locking balls to retract into a radial groove. This type has the widest range of types and sizes. Available in steel or stainless steel.

SIZES: Choice of four handle styles: T, L, Button, and Ring. Standard shank diameters from 3/16 to 1" (5 to 20mm in metric). Any grip length up to 6" (150mm in metric) is available as standard, at no extra charge. Available from stock in many standard grip lengths, or quickly made to order in custom lengths and diameters.

OPTIONAL STAINLESS MATERIAL: Pins are optionally available in stainless steel instead of alloy steel, for greater corrosion resistance. Note: both steel and stainless pins have aluminum handles and buttons. Add "-S" to the part number:
• CL-4-BLPR-1.50 (steel)
• CL-4-BLPR-1.50-S (stainless)

OPTIONAL 4 BALL: Pins are optionally available with four balls instead of two, for more-distributed ball-pullout force. Add "-4BALL" to the part number:
• CL-4-BLPR-1.50-S-4BALL

OPTIONAL CABLE: To order pins with a standard cable assembly attached (#2 cable size, 12" long, with a terminal at the free end for a #10 or M5 attachment screw), add "-C" to the part number:
• CL-4-BLPR-1.50-S-4BALL-C

• CL-4-BLHR-1.50-S (stainless handle)
• CL-4-BLHR-1.50-P (plastic handle)

OPTIONAL CABLE: To order pins with a standard cable assembly attached (#2 cable size, 12" long, with a terminal at the free end for a #10 or M5 attachment screw), add "-C" to the part number:
• CL-4-BLHR-1.50-S-C

MATERIAL (STAINLESS HANDLE): Shank > 17-4PH/15-7MO stainless, heat treated Rc 40 min. Spindle > 17-4PH/15-7MO stainless. Handle > 17-4PH stainless. R-handle ring > 302 stainless. Head and button > 303 stainless steel. Collar > 300-series stainless. Spring and ring > 17-7PH/302 stainless. Balls > 440C stainless. Note: alternative materials listed here are manufacturing options, not customer options.

MATERIAL (PLASTIC HANDLE): Same as above except handle is made of reinforced composite resin plastic (green).

 MARINE BALL LOCK PINS

FEATURES: Similar to our standard single-acting Ball Lock Pin in stainless steel, except this type has its handle and button made of 300-series stainless steel (instead of aluminum) for extra corrosion resistance in marine environments. Available only in stainless steel.

SIZES: Choice of two handle styles: Recessed Button (M), and Ring (R). Shank diameters from 3/16 to 1/2" (5 to 12mm in metric), each in a choice of many standard grip lengths. Available from stock only in the standard grip lengths listed (other grip lengths available as specials).

OPTIONAL CABLE: To order pins with a standard cable assembly attached (#2 cable size, 12" long, with a terminal at the free end for a #10 or M5 attachment screw), add "-C" to the part number:
• CL-4-MBPR-1.50-S-C

MATERIAL (STAINLESS): Shank > 17-4PH stainless, heat treated Rc 40 min. Spindle > 17-4PH stainless. Handle and button > 300-series stainless. Spring and ring > 17-7PH/302 stainless. Balls > 440C or 300-series stainless. Note: alternative materials listed here are manufacturing options, not customer options.

 ADJUSTABLE BALL LOCK PINS

FEATURES: These Ball Lock Pins have an adjustable grip length. They can be used for clamping, or simply to provide a variable grip length. The threaded handle turns to provide a 1/2" clamping range or adjustment range. When used just for variable grip length (not for clamping), the handle can be secured with the supplied knurled locknut. These single-acting pins are manufactured with four balls as standard, instead of two, for more-distributed ball-pullout force in clamping applications. Available in steel or stainless steel. Patent no. 3,101,641.

SIZES: Choice of three handle styles: Knob, T, and L. Standard shank diameters from 1/4 to 1" (6 to 20mm in metric), each in a choice of many standard grip lengths. Available from stock only in the standard grip lengths listed. Other grip lengths are available as specials (extra charge and longer delivery time).

OPTIONAL STAINLESS MATERIAL: Pins are optionally available in stainless steel instead of alloy steel, for greater corrosion resistance. Note: both steel and stainless pins have aluminum handles and buttons. Add "-S" to the part number:
• CL-4-ABPK-1.50 (steel)
• CL-4-ABPK-1.50-S (stainless)

OPTIONAL CABLE: To order pins with a standard cable assembly attached (#2 cable size, 12" long, with a terminal at the free end for a #10 or M5 attachment screw), add "-C" to the part number:
• CL-4-ABPK-1.50-S-C

MATERIAL (STEEL): Shank > 4130 steel, heat treated Rc 36-40, zinc plated. Spindle > 17-4PH stainless. T & L Handle > Aluminum alloy, black finish. Knob Handle > 319 aluminum alloy.

 DOUBLE-ACTING BALL LOCK PINS

FEATURES: Similar to a single-acting Ball Lock Pin, except the center spindle has two grooves instead of one, to release the balls by either pushing or pulling. Pushing on the handle releases the balls and inserts the pin in one motion. Pulling on the handle releases the balls and removes the pin in one motion. Available in steel or stainless steel.

SIZES: Choice of three handle styles: T, L, and Ring. Standard shank diameters from 3/16 to 1" (5 to 20mm in metric). Any grip length up to 6" (150mm in metric) is available as standard, at no extra charge. Available from stock in some standard grip lengths, or quickly made to order in custom lengths and diameters.

OPTIONAL STAINLESS MATERIAL: Pins are optionally available in stainless steel instead of alloy steel, for greater corrosion resistance. Add "-S" to the part number:
• CL-4-BPDR-1.50 (steel)
• CL-4-BPDR-1.50-S (stainless)

OPTIONAL DRIVE OUT: Double-acting pins are available with a "Drive-out" option, where the center spindle extends slightly beyond the shank end (see M dimension). This allows removing a pin under slight shear load by tapping the end with a hammer (releasing the balls at the same time). Add "-D" to the part number:
• CL-4-BPDR-1.50-S-D-4BALL

OPTIONAL 4 BALL: Pins are optionally available with four balls instead of two, for more-distributed ball-pullout force. Add "-4BALL" to the part number:
• CL-4-BPDR-1.50-S-D-4BALL

OPTIONAL CABLE: To order pins with a standard cable assembly attached (#2 cable size, 12" long, with a terminal at the free end for a #10 or M5 attachment screw), add "-C" to the part number:
• CL-4-BPDR-1.50-S-D-4BALL

MATERIAL (STEEL): Shank > 4130 steel, heat treated Rc 36-40, zinc or cadmium plated. Spindle > 4130 steel, cadmium plated, or 17-4PH stainless. Head, button, and handle > Carbon steel, zinc or cadmium plated. Spring and ring > 17-7PH/302 stainless, or music wire. Balls > 440C stainless. Note: alternative materials listed here are manufacturing options, not customer options.

MATERIAL (STAINLESS): Shank > 17-4PH/15-7MO stainless, heat treated Rc 40 min. Spindle > 17-4PH/15-7MO stainless. Head, button, and handle > 300-series stainless.
