Absolute Elevation: Professional Parallel Sets at Penn Tool Co.
When it comes to positioning a workpiece at the perfect height inside a machine vise, you need dependable, flat ground spacers that leave no room for error. At Penn Tool Co., we provide the high-accuracy spacing bars that manual machinists, toolmakers, and CNC operators rely on to raise their raw stock above the vise bed. For over 50 years, we’ve supplied the manufacturing community with tough, dependable parallels. They give you the rigid alignment needed for accurate cuts while protecting your vise jaws from tool damage.
Explore our extensive selection of matched ground bars, engineered to close tolerances so your parts sit completely level. Discover the parallel set options that streamline your daily setups, all available at competitive price points to maximize your tooling budget without putting your facility's commitment to precision at stake.
Symmetrical Spacing for Every Machine Vise
Simplify your part setup and eliminate angular errors by choosing from Penn Tool Co.’s comprehensive inventory of precision workholding spacers. We stock the exact thickness and height combinations required to handle any component layout in seconds.
Our catalog is built to support the high-demand workflows of modern toolrooms. For general milling and drilling tasks, a standard parallel sets layout or a durable steel parallel set offers the reliable, matched support needed to keep your part square to the spindle. If you frequently machine delicate, compact components or thin strips, utilizing a specialized thin parallel set ensures you maintain maximum jaw grip while keeping your cutting zone clear. For high-volume production cells, a dedicated vise parallel set or matching parallels for milling enables your operators to swap parts quickly without losing their reference height.
From a pocket-friendly machinist parallel set designed for quick cell tasks to an elite precision parallel set complete with an impact-resistant storage case, we have you covered. We proudly partner with trusted industrial brands, including Precise, SPI (Swiss Precision Instruments), and Value Collection, to ensure your machinist parallels and milling parallel set investments deliver flat, reliable performance day after day.

Modern Workholding Standards: Layout Trends Across the USA
While automated probing systems expand throughout modern machine shops in the USA, the physical reliability of a matched parallel set remains the foundation of fast manual and CNC vise setups.
-
- Wavy Spring Support Systems: A major trend in production cells is pairing a thin parallel set with wavy spring inserts to keep the bars pressed tight against the vise jaws during high-pressure clamping.
- Embossed Quick-Read Dimensions: Modern machinist parallels now feature deeply marked, easy-to-read height graduations on the face, enabling operators to grab the exact pair they need without checking with a caliper.
- Ultra-Thin Clearance Formats: To handle tight spatial constraints, toolrooms are prioritizing an 1/32-inch or 1/16-inch precision parallel set to maximize vertical jaw contact on short workpieces.
- Stress-Relieved Alloy Steel: High-end steel parallel set options undergo advanced heat-treating processes to prevent the bars from warping or twisting over time due to shop temperature changes.
- Enclosed Storage Systems: Machine shops are selecting a full milling parallel set packaged in a specialized layout rack to shield the precision ground edges from loose chips and accidental shop floor drops.
