Infinite Height Flexibility: Professional Adjustable Parallel Sets at Penn Tool Co.
Tired of working around the limits of standard, solid setup blocks? Eliminating dimensional constraints in your workholding setups demands high-flexibility hardware rather than a collection of rigid, fixed-size blocks. Penn Tool Co. has been the trusted source for adjustable workholding references since 1968. For over 50 years, Penn Tool Co. has supplied industrial facilities with the adjustable reference standards necessary to hold precise clearances.
Explore our extensive collection of adjustable spacing tools, each meticulously ground to close geometric tolerances to guarantee that the top and bottom faces remain perfectly parallel. Discover the specialized adjustable parallel set options that streamline your workpiece positioning, all featured at competitive price points to optimize your toolroom budget without compromising your shop's dedication to quality.
Infinite Variable Spacing for Vises and Milling Tables
Maximize your machine setup options by relying on Penn Tool Co.’s comprehensive inventory of expandable layout hardware. We offer the versatile tools necessary to match the specific slot depths, bore openings, or fixture clearances your project demands.
Our catalog is built around the strict requirements of modern part verification and chip-making. When standard, fixed-height bars fall short of your target dimension, incorporating adjustable parallels into your workholding lets you expand the tool to the exact opening size, which can then be locked and verified using a standard micrometer.
For general inspection work or cross-slide setups, choosing an individual adjustable parallel or a set of adjustable parallel bars allows you to level casting parts or support raw stock above a vise bed seamlessly. Whether you are running complex operations or simple prototypes, utilizing a specialized adjustable parallel tool helps you set fast, repeatable heights across multiple parts.
From a pocket-friendly milling adjustable parallels pack for your milling cell to an expansive adjustable parallels set machinist configuration supplied in a custom-fitted vinyl case, we have you covered. We proudly partner with world-renowned metrology manufacturers, including Starrett, TESA Brown & Sharpe, and SPI (Swiss Precision Instruments), so you can source authentic Starrett adjustable parallels and other elite hardware with absolute confidence.

Expanding Your Boundaries: Setup Trends Across the USA
While automation continues to transform high-speed production cells across the USA, the immediate mechanical utility of an adjustable parallel remains essential for rapid prototyping and short-run job shops.
- Go-No Go Slot Inspection: Technicians are increasingly using an adjustable parallel tool as a temporary, adjustable plug gage to quickly check the internal width of machined slots and non-standard keyways.
- High-Torque Twin Locking Screws: Modern machinist adjustable parallels utilize dual locking screws on larger sizes to prevent the overlapping wedges from slipping under high vise clamping pressures.
- Step-Less Height Tuning: American machine shops favor a complete adjustable parallel set because it replaces dozens of solid parallels, saving massive amounts of drawer space at individual work cells.
- Corrosion-Resistant Surface Treatments: Production lines now demand an adjustable parallel or adjustable parallels finished with high-durability tool steel coatings to resist rust from water-soluble CNC coolants.
- Vise-Clearing Profiles: Operators are selecting thin, specialized precision adjustable parallels to provide maximum cutter clearance when milling thin-walled workpieces close to the jaw face.
Maximize Your Machining Edge: The Penn Tool Co. Difference
An unverified work setup inevitably results in parallel deviations, out-of-tolerance shoulders, and broken cutting tools. Give your team the tools for flawless part positioning. Choosing top-tier machinist adjustable parallels or a comprehensive adjustable parallel set from Penn Tool Co. ensures repeatable accuracy across all your milling and layout bays Trust our five decades of industrial metrology experience to provide the dependable, high-accuracy setup tools that keep your business productive.
