Product Description
The Heli-Coil NAS1130-04-10D by Stanley Engineered Fastening is a military-standard tangless free-running insert engineered to provide durable, high-strength internal threads in lightweight or soft parent materials. Precision-rolled from high-quality 304 stainless steel wire with a diamond-shaped cross-section, this wire insert effectively balances joint load distribution by eliminating stress concentrations. Because it is completely tangless, this wire insert eliminates the multi-step process of breaking off and retrieving installation tangs, providing an ideal, debris-free fastening solution that protects sensitive aerospace, electronic, and defense assemblies against foreign object debris (FOD). It provides a permanently wear-resistant thread that defends assemblies against stripping, corrosion, and thread erosion.
Tangless Design Provides permanent, wear-resistant threads while completely eliminating the traditional need for tang break-off and retrieval, protecting critical systems from foreign object debris (FOD).
Free-Running Profile Delivers a clean, conventional internal thread that allows standard bolts and fasteners to turn freely through the precision-formed profile.
High Material Adaptability Seamlessly adjusts to the natural thermal expansion and contraction of the parent material to maintain a permanently anchored fit within the tapped hole.
Premium Wire Construction Features precision-formed, diamond-shaped wire that requires no staking, swaging, keying, locking, or interference fits during installation.
