SpecialInsert F1 Female Bonding Fastener, 38 mm, 1/2-13

Description

The SpecialInsert F1 bonding fastener creates a female 1/2-13 attachment point on metal, composite, plastic, stone, and other bondable surfaces. Its 38 mm round base spreads load across the adhesive area, while the zinc-plated steel nut accepts a standard mating bolt after the adhesive has cured.

Where the F1 Female Fastener Works

This hardware supports blind-hole and through-hole assembly when drilling or welding is undesirable. Common uses include access panels, signs, marine interiors, transportation components, equipment enclosures, countertops, furniture, and composite structures. The female thread helps with bolt alignment and allows the attached part to be removed later without disturbing the bonded base. The round plate also provides broad adhesive contact.

SpecialInsert F1 Bonding Fastener Installation

Prepare the substrate and base for the selected structural adhesive, then apply enough material to wet the perforated bonding area without flooding the central nut. Seat the fastener square to the surface, maintain position during cure, and keep adhesive out of the internal threads. The final joint depends on the adhesive, surface preparation, bond-line control, substrate strength, cure conditions, and load direction. Complete a representative test whenever the assembly carries critical weight or sees vibration.

Specifications

Pair the fastener with an adhesive suited to both the base metal and substrate. Protect the threads during bonding, allow the full specified cure, and tighten the mating bolt within the limits of the complete assembly.
