Feeler & Pitch Gauge Sets

Proto J000SL feeler gauge set with 12 long blades in hardened steel. Extended blade length reaches deeper into assemblies than standard feeler gauges. Used by mechanics, machinists, and equipment...

Metric screw pitch gage with leaves matched to standard metric thread pitches. Each leaf identifies an unknown metric thread on bolts, taps, and fittings for the right replacement. Folds into a...

Proto J000AA feeler gauge set with 25 blades in SAE thicknesses. Hardened steel blades measure clearance and gap dimensions during precision assembly, valve adjustment, and machinery installation...

Proto J00MM25 feeler gauge set with 25 blades in metric thicknesses. Hardened steel blades measure clearance and gap dimensions during precision assembly, valve adjustment, and machinery installation...

Screw pitch gage with 30 leaves for checking 60 degree threads. Each leaf matches a thread pitch, so the gage identifies unknown threads on bolts, taps, and fittings for the right replacement. Folds...

Proto J000M feeler gauge set with 11 blades in hardened steel. Hardened steel blades measure clearance and gap dimensions during precision assembly, valve adjustment, and machinery installation work...

Irwin Hanson 18-blade SAE thread pitch gauge. Hardened steel blades measure thread pitch on fasteners and threaded stock during identification work. Larger blade count than 16-blade gauge covers...

Proto J000J feeler gauge set with 6 blades configured for spark plug gap measurement. Hardened steel blades measure spark plug gap during automotive and small engine service. Used by mechanics and...

Metric screw pitch gage with a range of leaves for identifying metric thread pitches. Matching a leaf to the thread reveals the pitch on bolts, taps, and fittings for correct replacement. Folds into...

Metric screw pitch gage with 28 leaves for identifying metric thread pitches. Each leaf matches a pitch to read unknown threads on bolts, taps, and fittings for correct replacement. Folds into a...

Proto J000BR feeler gauge set with 6 blades in non-magnetic construction. Non-magnetic blades support measurement around sensitive electronic and magnetic equipment. Hardened steel blades measure...

Proto J000TL feeler gauge set with 25 long blades in hardened steel. Extended blade length reaches deeper into assemblies than standard feeler gauges. Used by mechanics, machinists, and equipment...
