Precision Two-Part Handle Fasteners — Brass, Stainless Steel & Titanium

KnifeKits.com® is pleased to introduce Gulso Bolts — a precision two-part handle fastener system built for custom fixed-blade construction. Available in two sizes and three premium materials, these bolts are engineered for builders who demand a clean, flush, tactical result from their handle work.

Size 01 — Standard

Gulso Bolt — .250HD × 0.155BD × 0.575–0.820 OAL


Brass · Stainless Steel · Titanium — Single or 10-Pack

The Standard Gulso Bolt delivers a compact profile suited to a wide range of handle scales and tang dimensions. The threaded post passes through the tang hole and scale material; the mating screw draws both heads down to create a firm pinch on each face of the handle. Once tightened with a T-15 TORX® driver, the bolt can be sanded flush for a clean, intentional fastener aesthetic. Accepts epoxy and thread-locker for permanent assembly.

Key Advantages

  • Compact .250″ head suited to narrow scales and refined tang profiles

  • 3mm thread engages reliably across natural and synthetic handle materials

  • T-15 TORX® drive eliminates cam-out when torquing into hardwoods and composites

  • Brass, Stainless Steel, or Titanium — match your blade hardware and finish intent

  • Flush-sanding capability for an uninterrupted handle surface

  • Epoxy and thread-locker compatible for permanent bonding

Size 02 — Heavy-Duty

Gulso Bolt — .375HD × 0.246BD × 0.625–0.885 OAL

Stainless Steel · Brass · Titanium — Single or 10-Pack

The Heavy-Duty Gulso Bolt is the correct choice for thick handle slabs, full-tang working knives, and any build where structural rigidity at the fastener point is non-negotiable. The enlarged .375″ head distributes clamping load across a wider footprint, reducing compression risk on softer scale materials. The US 8-32 thread holds cleanly under torque, and the same T-15 TORX® interface as the standard size means no tooling change between builds.

Key Advantages

  • Broader .375″ head spreads clamping force — ideal for thick or softer scale materials

  • US 8-32 thread delivers proven engagement strength for heavy-use builds

  • Wider .246″ barrel resists lateral shear through the handle assembly

  • Shared T-15 TORX® driver keeps shop tooling consistent across both bolt sizes

  • Flush-sanding finish maintains clean, uninterrupted handle surface lines

  • Stainless Steel, Brass, or Titanium for full control of weight and corrosion resistance

Material Selection Guide
Brass, Stainless Steel, or Titanium — Which Is Right for Your Build?

Brass

Warm Tone & Classic Character

Brass offers a rich gold appearance that polishes to a high luster and develops a natural patina over time. It is the easiest of the three to sand flush and dress cleanly. Best paired with natural handle materials — wood, bone, stag, and horn — where a warm, traditional fastener aesthetic is the goal. Heavier than titanium, which can add desirable forward balance on smaller blades.

Stainless Steel

Versatile & Corrosion Resistant

Stainless Steel is the all-purpose choice. A clean, neutral silver tone works with virtually any handle material and finish direction. Excellent corrosion resistance makes it well-suited to working knives, outdoor and field builds, and any knife likely to see moisture or hard use. The standard weight reference for the Gulso Bolt line — neither heavy nor light.


Titanium

Lightweight & Field-Ready


Titanium delivers superior corrosion resistance and the lowest weight of the three options — the preferred choice for EDC and tactical builds where every gram is accounted for. Well-suited to knives destined for harsh environments. Work slowly with sharp tooling when sanding flush; titanium rewards patience and proper abrasive selection.


FROM THE BENCH

Every knife tells the story of the hands that built it. The hardware you choose is part of that story — visible, tactile, and permanent. Gulso Bolts are built to hold that standard.


We appreciate your craft and your business. As always, if you have questions about fit, sizing, or material selection for your specific build, our team is here to help.
