Best Application

Budget workshop requiring accurate 1-2-3 references for layout, squaring, and jig setup in metal or woodworking.

Investment Value

Great Value

Durability Index

Durable steel construction; expect long service life with proper care; surfaces may wear with heavy use.

Key Buying Points

Two-pack provides extended reference options and the ability to stack for larger layout references.

User-reported accuracy ranges within a few ten-thousandths to a few thousandths of an inch, sufficient for most shop tasks.

Five threaded 3/8-16 UNC holes offer basic fixture mounting and jig engagement for common setups.

Hardened steel construction yields heft and stable reference during measurement and layout checks.

Significantly more affordable than premium brands, delivering strong value for budget-conscious shops.

Compatible with calipers, table saw alignment checks, and various metrology tasks in wood or metalworking.

Compact 3x2x1 inch size fits easily on small benches and tool chests.

The Catch

Not a premium, Starrett-grade level of precision; tolerances are suitable for general reference but not high-precision work.

Not designed for bolt-through connections; holes are not drilled to pass bolts for secure multi-block fixtures.

Tolerances can vary between blocks and may require light lapping or truing for perfect squareness.

Occasional packaging or handling concerns reported by some buyers.

Limited to two blocks; larger reference sets may be needed for wide-range layout tasks.

Common Questions & Expert Insights

Q: Can I bolt blocks together through holes?
Not suitable for bolt-through connections. The holes are not bored to pass bolts, so bolting blocks together is limited.)
Q: Are these blocks as precise as premium brands?
Not Starrett-grade precision. These are budget blocks with tolerances in the thousandths range, suitable for general layout but not high-precision metrology.)
Q: Are there quality control issues I should know about?
Quality control can vary. Some units square up well; others may show minor high spots that welcome light lapping.)
Q: Will these blocks work with calipers and DRO setups?
Yes, they work with calipers and DRO references. They serve well as fixed references for distance checks and layout checks.)
Q: Can I mount them reliably in fixtures using the holes?
Holes support basic fixture mounting. The five threaded holes enable simple fixture engagement, not heavy-duty clamping.)
Q: How should I maintain accuracy over time?
Regular cleaning helps maintain accuracy. Wipe surfaces after use and periodically recheck with calipers.)
Q: Should I lap the faces for best flatness?
Lapping may improve flatness. If near-perfect squareness is required, light surface finishing can help.)
Q: How do they compare to other budget 123 blocks?
Cheaper alternative with basic accuracy. They compare favorably for casual shop use, though not as precise as premium options.)
Q: Are bolt-through options better for fixtures?
Bolt-through solutions exist elsewhere. If you need through-bolts, seek blocks designed for that feature.)
Q: What material are these blocks made from?
Hardened steel construction. The blocks are built from hardened steel for wear resistance in typical shop use.)
