The Nexxus Alloy Outserts 400 is a 12-pack of 50-grain outserts built for archers shooting .400 spine micro-diameter arrows. Each unit pairs a 20-grain pin with a 30-grain sleeve, both machined from 7075 aluminium, to reinforce the front of the shaft where impact stress concentrates. These outserts accept standard 8-32 thread points and broadheads, so they drop into a typical hunting or target setup without special hardware. For bowhunters running Nexxus Infinity shafts in the 4.2mm/.166 ID class, this is the component that ties shaft, point, and broadhead together. Browse the full range in our arrow inserts selection.
The design uses an interlocking pin-and-sleeve combination rather than a single-piece insert. The pin seats inside the shaft while the sleeve wraps the outside diameter, distributing impact load across a larger surface and protecting the carbon at the point end. Dual locking threads hold the assembly in precise alignment between the arrow, the outsert, and the broadhead, which keeps the cutting edge concentric to the shaft for cleaner flight and consistent point-on. The 7075 aluminium gives you the strength for repeated target and field use without adding excess mass up front. At 50 grains total, the package adds meaningful weight forward to stabilize broadheads while keeping the front end durable. Compare it against the heavier-duty Nexxus titanium outsert if you want more weight or impact resistance.
Hunters chasing big game put a lot of trust in the front of the arrow, and that is where this outsert earns its keep, soaking up the shock of bone and hard angles while keeping the broadhead spinning true. Target archers shooting micro-diameter shafts get the same alignment benefit for tighter groups at distance. If you run a heavier or lighter spine, Nexxus offers matched options like the Alloy Outserts 300 and the Alloy Outserts 250 to match your shaft. Pick the spine that fits your arrows and stock a few spares before the season opens.
They are designed for .400 spine Nexxus Infinity micro-diameter shafts in the 4.2mm/.166 inside-diameter class. The pin seats inside the shaft while the sleeve wraps the outside, so they are matched to that shaft size rather than a universal fit.
Each outsert weighs 50 grains total, made up of a 20-grain pin and a 30-grain sleeve. That weight sits at the front of the arrow to add forward stabilization for broadheads and field points.
They accept standard 8-32 thread pitch points and broadheads, which covers the majority of hunting and target heads on the market. No proprietary thread or adapter is required.
Both share the same 8-32 thread and shaft compatibility. The 7075 aluminium version keeps the front end lighter and is built for repeated field and target use, while the titanium version offers added weight and impact resistance for hunters who want more mass and durability up front.
Each package contains 12 outserts, enough to outfit a full dozen arrows. Many shooters keep an extra pack on hand for replacements after hard impacts or lost arrows.
