The metalworking shop standard for ultra-precise workholding, rigid part elevation, and flawless milling machine vise setup.

When staging complex workpieces in a milling vise, maintaining absolute parallelism is non-negotiable. The MHC Industrial Supply 9-Pair Precision Parallel Set (Model 637-7035) is the definitive setup system relied on by professional machinists, toolmakers, and CNC operators. Arriving brand new in a fitted hardshell protective organizer case, this heavy-duty 1/4" thick master collection ensures structural rigidity and exact part positioning across a versatile spectrum of milling, drilling, and grinding applications.

Forged from premium, high-quality alloy steel, every parallel bar in this set is meticulously hardened to a rugged HRC 55–62 threshold and precision-ground on all four functional surfaces. Each of the 9 matched pairs delivers a tight, high-tier tolerance threshold of ±0.0003" accuracy for both parallelism and paired height similarity. Spanning a 3/4" to 1-3/4" height range in flawless 1/8" increments, these 6-inch long bars feature a two-hole weight-reduction design to make part change-outs swift and effortless.

Key Features & Benefits

  • Premium 1/4" Heavy-Duty Thickness: Extra-thick architectural design provides massive structural resistance against lateral jaw pressure, completely eliminating bar flex or tipping under high torque clamping.

  • Ultra-Precise Matching Tolerances: Ground to a strict ±0.0003" tolerance window, ensuring perfectly flat part registration and repeatable machining dimensions from part to part.

  • No-Skip 9-Pair Setup Spectrum: Comprehensive incremental selection ranging from 3/4" up to 1-3/4" heights to keep your workpiece perfectly elevated above the vise base.

  • Hardened Alloy Steel Construction: Heat-treated to a heavy industrial HRC 55–62 rating, providing supreme resistance against scratches, ambient shop dings, and surface deformation.

  • Two-Hole Weight Reduction Profile: Pre-machined with dual through-holes to optimize balance, ease extraction from deep vise jaws, and reduce overall setup weights.

  • Heavy-Duty Compartment Storage Case: Arrives completely organized in a impact-resistant case to guard your ground surfaces against grit, corrosion, and tool-on-tool collision.
