ZSHJGJR 31-Inch Carbon Arrow Shafts | 6.2mm ID, Spine 340/400/500/600 for DIY Arrows

Overview

The ZSHJGJR 31-Inch Carbon Arrow Shafts are bare, raw carbon tubes designed for builders who want to tailor their own hunting arrows. Measuring 31.1 inches (79 cm) long, each shaft balances stiffness and weight to support a versatile DIY platform. With an internal diameter of 6.2 mm, these shafts accommodate standard components, while the four spine options—340, 400, 500, and 600—let you tune flex to your bow and draw weight. This combination aims to help you approach flight consistency from bench setup to field use without committing to a single ready-made configuration.

Built for consistency and lightness

Crafted from pure carbon, these shafts deliver a light, balanced feel that maintains a steady line in flight. The straightness tolerance is tight, with a maximum deviation of ±0.006 inches, aiding builders who chase predictable flight paths once the arrow is fletched and tipped. Each shaft weighs about 15.8 g, keeping overall arrow mass manageable for a range of setups—whether you’re tuning for distance, accuracy, or field reliability.

• Carbon arrow shaft length: 31.1"/79 cm; ID 6.2 mm; spine 340/400/500/600; straightness ±0.006".
• Pure carbon construction offers durability, lightweight performance, and reliable balance for DIY arrow building.
• Compatible with compound bows, recurve bows, longbows, and traditional setups.
• Lightweight at about 15.8 g per shaft, aiding batch building and tuning.
• Packaging options include 6 pcs, 12 pcs, or 24 pcs per package.

How to choose the right spine

The spine you pick affects how the arrow flexes in flight. Heavier draw weights or stiffer bows often pair with higher spine numbers (like 500/600) for a steadier trajectory, while lighter setups may benefit from 340–400 spines for quicker stabilization after release.

• Match spine to bow type and draw weight for stable flight.
• Consider arrow weight and tip configuration when selecting spine.
• Test different spines to discover the feel you prefer for practice and hunting.

Bundles for DIY projects

Whether you’re building a handful of practice arrows or a full quiver, these shafts come in convenient bundles: 6, 12, or 24 shafts per package. The bare raw shafts invite you to customize with your choice of tips, nocks, and fletching, letting you tailor the arrow’s balance and flight characteristics to your setup.

Material and performance notes

As bare carbon tubes, they’re ready for your finishing touches. The weight and diameter are consistent across spines, helping with predictable spine-to-tip alignment as you assemble each arrow piece by piece.
