Value Collection 526030PS M3 X 0.50 Hex Jam Nut Grade 2H Zinc

Product Description

The VALUE COLLECTION 526030PS is an M3 x 0.50 hex jam nut manufactured from Grade 2H steel with a zinc-plated finish. Jam nuts are thin hex nuts used primarily as locknuts to secure a standard hex nut in place or in applications where limited axial space requires a lower-profile fastener. At 1.80 mm in height and 5.50 mm across flats, this nut meets the dimensional requirements of DIN 439 and ISO 4035. The zinc coating provides a basic level of corrosion resistance suited to general indoor and light-duty applications. Trade professionals and assembly technicians will find this nut appropriate for light mechanical and electrical panel assemblies.

This jam nut is used in residential and commercial applications where an M3 x 0.50 metric thread is required and vertical clearance is limited. Typical scenarios include securing terminal studs on electrical enclosures, locking adjustable components on HVAC controls, and general machine assembly requiring a thin locking element. Right-hand thread direction is standard, making it compatible with conventional M3-threaded fastener assemblies across a wide range of trade and industrial applications.

Key Features

• Jam nut profile at 1.80 mm height conserves axial space in tight assemblies
• Grade 2H steel construction provides adequate strength for light-duty metric fastening
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered environments
• Conforms to DIN 439 and ISO 4035 dimensional standards
• Right-hand thread direction for compatibility with standard M3 x 0.50 threaded components
• 5.50 mm across flats fits standard metric wrenches and nut drivers

Compatibility

Designed as an OEM-style replacement or general-use jam nut for any application requiring an M3 x 0.50 right-hand thread metric fastener conforming to DIN 439 or ISO 4035 dimensional standards.

Installation Notes

Installation requires a standard metric wrench or nut driver sized for 5.50 mm across flats. When used as a locknut, thread the jam nut against the primary nut and hold the primary nut stationary while tightening the jam nut to create the locking preload. De-energize any electrical panel or control circuit before working on terminals secured by these nuts. Do not exceed the load limits appropriate for Grade 2H M3 hardware.
