Product Details

The ARP 641-3750 is a premium 5-piece bolt kit featuring 12-point head fasteners designed for differential, ring and pinion, and general automotive, marine, and trailer applications. These high-performance bolts are manufactured from specially alloyed ARP 300 stainless steel with a polished finish that delivers both exceptional strength and corrosion resistance.

Key Features:

  • Nominally rated at 180,000 psi tensile strength for superior clamping force
  • 12-point head design for improved grip and reduced risk of rounding
  • ARP 300 stainless steel construction resists rust and corrosion
  • Polished stainless finish provides professional appearance
  • Includes matching washers for complete installation
  • Significant safety margin over standard Grade 8 hardware

ARP fasteners are engineered to exacting tolerances and provide maintenance-free performance in demanding environments. The 12-point head design allows for easier installation in tight spaces with finer angle increments compared to standard hex heads. Each kit includes five bolts with washers, ready for installation.

Great quality and and I received very quickly.

best price I can find on a motive brake bleeder anywhere. shipped same day - now that's great service!

best price on the net, GREAT communication.....

best price i have seen while i am searching in the interner :))

Good price on my THU-A90275. Had to contact customer service...they were professional and eventually resolved my concern. Called over the phone and the guy told me he couldn't help me with a coupon/refund, but that I had to contact support via email (I guess the phone support and email support aren't one and the same). It took a couple emails, but eventually they refunded me what was due.
