Value Collection JN9X00300-200BX M3 X 0.50 Hex Nut 200-pack

Product Description

The VALUE COLLECTION JN9X00300-200BX is an M3 x 0.50 hex nut manufactured from 18-8 austenitic stainless steel conforming to Grade A2 classification. It meets the DIN 439B fastener standard, which designates it as a thin or jam nut profile with a height of 1.80 millimeters. The bright, uncoated finish leaves the base stainless steel exposed, providing inherent corrosion resistance without additional surface treatment. These nuts ship in a minimum order quantity of 200 pieces, making them suitable for production runs, maintenance stock, or kitting applications where consistent metric fastener supply is required. Licensed tradespeople working in HVAC, plumbing, electrical, and light mechanical applications will recognize this as a standard metric jam nut for M3 threaded fastener assemblies.

This hex nut is used wherever an M3 x 0.50 metric thread engagement is needed in corrosion-resistant assemblies. Typical applications include light-duty equipment panels, control enclosures, condensate drain hardware, and instrumentation mounting where stainless steel is specified to resist moisture or mild chemical exposure. The thin jam-nut profile per DIN 439B allows use in space-constrained fastening scenarios or as a locking element against a primary nut. Sold in multiples of 200, this SKU is well suited for shop stock and service van inventory.

Key Features

• M3 x 0.50 metric thread, right-hand direction, conforming to DIN 439B thin hex nut standard
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant without plating or coating
• Bright uncoated finish — no coating thickness to affect thread tolerance or torque values
• 5.50 mm across flats, compatible with standard M3 open-end and combination wrenches
• 1.80 mm height — low-profile jam nut geometry for tight-clearance or locking applications
• Packaged in quantities of 200 for efficient stocking and production use

Compatibility

Designed for use with M3 x 0.50 metric threaded fasteners and studs in assemblies specifying DIN 439B thin hex nuts in 18-8 or A2 stainless steel.

Installation Notes

Install with a standard 5.50 mm open-end or combination wrench. As a thin jam nut, this fastener is commonly torqued against a primary nut or shoulder to create a locking interface — do not substitute for a full-height structural nut where load-bearing engagement is required. Ensure threads are clean and free of debris before assembly. Follow applicable equipment manufacturer torque guidelines for M3 metric fasteners when specified.
