The Big Horn Spring Caliper/Divider Set combines hardened points, forged legs and a self-seating adjusting screw so marks stay repeatable and adjustments are quick. Are these robust and precise enough for regular workshop use and beginner projects?
⚡ At a Glance
- • Measurement Accuracy: Hardened points and forged legs deliver repeatable measurement transfer
- • Best for: DIYers, metalworkers and beginners learning scribing and diameter gauging
- • Not ideal for: Precision calibration tasks requiring certified, traceable instruments
Three 8-inch spring calipers/dividers are forged from high-carbon steel with hardened points. Adjustment uses a self-seating washer and nut plus hardened bow springs for uniform tension.
Accurate external measurement - with an 8-inch outside caliper and hardened points
Forged high-carbon steel legs and hardened points create firm contact against external surfaces, while hardened and tempered bow springs maintain consistent tension and alignment.
External diameters and contours can be transferred to a ruler reliably, useful when checking shafts, collars or matching fittings.
Precise internal gauging - with an 8-inch inside caliper and tempered springs
Inside caliper uses the same hardened legs and bow springs so the span remains steady inside openings, and fulcrum spools reduce side play during measurement.
Inner diameters of pipes and bores can be gauged and then marked or recorded without repeated fiddly adjustments.
Scribing and contour tracing - with a flat leg divider and self-seating screw
Flat leg divider features hardened points and an adjusting screw with a self-seating washer and nut to permit quick, positive micro-adjustments across uneven surfaces.
Tracing contours or scribing circles into metal or wood becomes more consistent, saving time when transferring patterns or laying out cuts.
